Description

Technical Field

[0001] The invention relates to a conveyor, in particular to a sand feeder with a rinsing function. Background Art

[0002] Existing electrolytic sand washing feeding equipment is conventional conveying equipment, using belt conveyors or screw conveyors. These equipment cannot remove shells, seaweed, silt, large pieces of sand and other debris in the sea sand. Shells, seaweed, silt and other debris enter the subsequent equipment sand washing machine with the conveying equipment, often causing the sand washing machine to get stuck, affecting production efficiency. And the debris will accumulate in a very short time, causing the electrolytic equipment in the sand washing machine to short-circuit. The debris sand is also easy to enter the electrolytic equipment of the sand washing machine, affecting the product quality (the debris contained in the sand has no market value), and it is also easy to cause a short circuit, which seriously affects the life of the electrolytic equipment, making it difficult for the equipment to operate stably for a long time. And the sea sand containing a large amount of silt (a mixture of silt and sea sand) cannot be processed. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the problem to be solved by the present invention is to provide a sand loader with a rinsing function which can effectively remove impurities in sea sand, improve sand product quality, and prevent short circuit of electrolytic equipment.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] The present invention provides a sand loader with a rinsing function, which adopts a screw conveying device, including 1 to 2 screw conveying rods connected in parallel, which are installed in a trough body, the head end and the tail end of the 1 to 2 screw conveying rods connected in parallel are connected through a gear set transmission, and the input end of the tail end gear set is connected to the output end of a driving motor; the inlet side of the screw conveying device receives the poured raw sea sand, and the outlet side is arranged above the sand inlet of the next-level electrolysis equipment, and a connecting guide groove is provided between the loader and the electrolysis equipment.

[0006] The first section of the spiral blades on the main shaft of the spiral conveying equipment is solid, and the connection between the remaining spiral blades and the main shaft adopts a hollow structure.

[0007] A set of stirring blades is arranged at the rear end of the first section of the main shaft.

[0008] One end of the connecting guide groove is connected to the fresh water tank in the sand washing machine, and the other end is connected to the tank body of the electrolysis equipment. The inlet side of the connecting guide groove is lower than the fresh water level line of the fresh water tank.

[0009] The present invention has the following beneficial effects and advantages:

[0010] 1. The present invention provides a sand feeder with a rinsing function, which can effectively remove 95% of the debris in the sand. Sand with a mud content of less than 30% does not need any other treatment and can be directly fed into the machine for processing, which greatly reduces the equipment cost and improves the product quality of the finished sand.

[0011] 2. The present invention effectively protects the electrolytic equipment and prevents electrolytic short circuit. It reduces the jamming of the relevant mechanisms of the sand washing machine and affects the production efficiency. At the same time, it protects the stable operation of the electrolytic device and can run smoothly in the sea sand processing equipment with large amount of impurities.

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] like Figures 1-2 As shown, the present invention provides a sand loader with a rinsing function, which adopts a screw conveying device, including 1 to 2 parallel-connected screw conveying rods, which are installed in a trough body 7, and the head end and the tail end of the 1 to 2 parallel-connected screw conveying rods are connected by a gear set transmission, and the input end of the tail end gear set is connected to the output end of the driving motor; the inlet side of the screw conveying device receives the poured raw sea sand, and the outlet side is arranged above the sand inlet of the next-level electrolysis equipment 1, and a connecting guide groove 6 is provided between the loader 2 and the electrolysis equipment 1.

[0017] The first section of the spiral blades of the main shaft of the screw conveying equipment is solid, and the connection between the remaining spiral blades 3 and the main shaft adopts a hollow structure; a group of stirring blades is provided at the rear end of the first section of the main shaft; one end of the connecting guide groove 6 is connected to the fresh water tank in the sand washing machine 2, and the other end is connected to the tank body 7 of the electrolysis equipment 1, and the inlet side of the connecting guide groove 6 is lower than the fresh water level line 8 of the fresh water tank.

[0018] In this embodiment, the water level of the fresh water level line 8 of the fresh water tank in the electrolysis device 1 is 80 mm higher than the water level of the sand washing machine connecting guide groove 7. When the machine is turned on, fresh water is regularly added to the electrolysis device 1 so that its liquid level is always kept 80 mm-90 mm higher than the water level of the guide groove.

[0019] The first section of the spiral blade of the main shaft of each screw conveyor rod is solid, and the connection between the remaining spiral blades 3 and the main shaft adopts a hollow structure. This structure facilitates the separation of water and sea sand. During the conveying process, the equipment rotates. Since the density of sand is large, it settles at the lower layer. With a spiral diameter of 1.5 meters and a blade width of 200 mm, the sea sand at the bottom layer of the equipment is conveyed forward. Impurities such as silt have a density smaller than that of sea sand and will float along with the water flow. The direction of the water flow is opposite to the direction of sea sand conveyance. The water flow flows in the opposite direction to the conveyance direction along the hollow position of the spiral, clearing the silt to a position opposite to the conveyance direction. At the rear end of the first section of the main shaft, stirring blades 4 are designed. Under the action of the stirring blades, the sea sand rotates and stirs repeatedly, achieving full mixing. Large lumps of sand and silt are fully stirred and mixed. The silt and other impurities in the sea sand are quickly separated from the sand. Since the silt and other impurities have a density smaller than that of sea sand, they float on the upper layer with the water and flow away from the gap between the spiral blade 3 and the main shaft, and finally are discharged from the sewage outlet 9.

[0020] A set of solid spirals is designed at the first section of the main shaft, which is in the same direction as the sand conveyance direction. The solid spirals can prevent foreign matters from flowing towards the bearings at the first section, protecting the bearings of the transmission mechanism, the sealing structure, etc. The connecting guide groove 6 configured in the present invention is connected to the electrolysis equipment, and the water level is more than 80 mm lower than that of the electrolysis spiral. By cleverly using the by-product of the electrolysis process - hypochlorous acid, the backflow is realized for rinsing. The liquid level difference makes the water flow from the electrolysis spiral to the rinsing spiral, and the hypochlorous acid also flows to the rinsing spiral. The hypochlorous acid corrodes the organic film on the surface of the sea sand, and with the cooperation of the stirring blades 4, the hypochlorous acid and the sea sand are in full contact. This makes it very easy to clean the sea sand. During the conveying process, the silt in the sea sand is effectively removed, preventing the electrolysis equipment from short-circuiting, reducing the jamming of the electrolysis spiral and affecting the production efficiency, and protecting the stable operation of the electrolysis equipment. It can operate smoothly in the sea sand treatment equipment with a large amount of sediment. The sea sand with the organic film removed is easier to electrolyze. Moreover, the quality of the sand product is improved (impurities, silt, etc. are removed).
