Description

Technical Field

[0001] This utility model relates to the technical field of river sand filtration equipment, specifically a device for filtration of river sand. Background Technology

[0002] River sand refers to building materials with certain quality standards formed in river water through the natural forces of the river, the impact and erosion of the water. Because of its hard texture and clear color, it is a good building material. Since river sand contains a large amount of mud, it needs to be washed before use to improve its cleanliness and thus improve the quality of concrete.

[0003] After washing, river sand needs to be filtered to separate the sand particles from the water and remove the moisture to reduce the water content of the river sand.

[0004] Currently, the common method to remove water from river sand is to expose it to the sun and evaporate the water, or to pass a mixture of river sand and water into a hydrocyclone separator to separate the water and sand particles. The former has low filtration efficiency, while the latter results in the accumulation of sludge on the inner wall of the cylinder, poor material discharge, and some water flowing out with the sand particles during the discharge process, which affects the filtration efficiency of the river sand. Utility Model Content

[0005] The purpose of this invention is to provide a device for filtering river sand, which has the characteristics of separating sand particles from water in two stages, effectively separating sand particles from water, reducing the water content of river sand, and thus improving the filtration efficiency of river sand.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a device for filtering river sand, comprising a sand removal cylinder and a sand storage cylinder connected to the bottom of the sand removal cylinder, wherein a second motor is installed on the bottom end face of the sand storage cylinder, the output end of the second motor passes through the bottom end face of the sand storage cylinder and is equipped with two rotating rods distributed to the left and right, and scrapers that abut against the inner side wall of the sand storage cylinder are installed on the upper ends of the two rotating rods that are relatively far from one end; the bottom of the outer side wall of the sand storage cylinder is connected to a conveying cylinder through a discharge pipe with a valve.

[0007] A third motor is installed on the right side wall of the conveying cylinder. The output end of the third motor passes through the right side wall of the conveying cylinder and is equipped with a spiral conveying rod. Multiple evenly distributed water outlet holes are opened through the bottom of the outer side wall of the conveying cylinder. A fixing frame is provided on the outer side wall of the conveying cylinder. Multiple connecting rods distributed front and back are installed between the inner side wall of the fixing frame and the outer side wall of the conveying cylinder.

[0008] In order to generate swirling and axial eddies in the liquid, which can accelerate the sedimentation of sand particles in the water, as a preferred device for filtering river sand according to the present invention, the upper end face of the sand removal cylinder is penetrated and a rotating cylinder is installed through a mechanical seal, the bottom of the rotating cylinder extends into the interior of the sand removal cylinder and multiple stirring blades are installed on the outer side wall.

[0009] In order to drive the rotating cylinder to rotate, as a preferred embodiment of the device for filtering river sand according to this utility model, a first motor is installed on the upper end face of the sand removal cylinder, a first bevel gear is installed on the output end of the first motor, and a second bevel gear installed on the outer side wall of the first bevel gear is meshed with the outer side wall of the rotating cylinder.

[0010] To facilitate the drainage of water from the fixed frame, the fixed frame is preferably semi-circular and connected to a drain pipe at the bottom, which is a preferred embodiment of the present invention for filtering river sand.

[0011] To facilitate the discharge of the separated sand particles, as a preferred embodiment of the device for filtering river sand according to this utility model, the outer wall of the conveying cylinder is connected to a discharge pipe located on the right side of the fixed frame.

[0012] To facilitate the introduction of the sand and water mixture into the sand removal cylinder and the discharge of the separated water, as a preferred embodiment of this utility model for filtering river sand, the left side wall of the sand removal cylinder is connected to an inlet pipe, the top of the rotating cylinder is equipped with an outlet pipe, and the top of the rotating cylinder and the outlet pipe are both mechanically sealed, and the second motor and the bottom end face of the sand storage cylinder are both sealed.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention introduces a mixture of water and river sand into the sand removal cylinder. Through the cooperation of a first motor, a first bevel gear, a second bevel gear, a rotating cylinder, and multiple stirring blades, the sand particles in the water can be accelerated to settle into the sand storage cylinder, thus initially separating the water flow from the sand particles.

[0015] By opening the valve on the feed pipe and starting the second motor, the sand particles are accelerated through the feed pipe and fall into the conveying cylinder. The sand particles are then conveyed by rotating the screw conveyor. Residual water in the sand particles can be discharged through multiple water outlets and drain pipes. The separated sand particles are discharged from the discharge pipe, further separating the sand particles from the water. This process of filtering the sand particles and water twice effectively separates the sand particles from the water, reduces the moisture content of the river sand, and thus improves the filtration efficiency of the river sand.

[0020] Please see Figures 1 to 3 A device for filtering river sand includes a sand removal cylinder 1 and a sand storage cylinder 2 connected to the bottom of the sand removal cylinder 1. A second motor 4 is installed on the bottom end face of the sand storage cylinder 2. The output end of the second motor 4 passes through the bottom end face of the sand storage cylinder 2 and is equipped with two rotating rods 401 distributed on the left and right. The upper ends of the two rotating rods 401 that are relatively far from one end are each equipped with scrapers 402 that abut against the inner side wall of the sand storage cylinder 2. The bottom of the outer side wall of the sand storage cylinder 2 is connected to a conveying cylinder 5 through a discharge pipe 201 with a valve.

[0021] A third motor 501 is installed on the right side wall of the conveying cylinder 5. The output end of the third motor 501 passes through the right side wall of the conveying cylinder 5 and is equipped with a spiral conveying rod 502. Multiple evenly distributed water outlet holes 503 are opened through the bottom of the outer side wall of the conveying cylinder 5. A fixing frame 6 is provided on the outer side wall of the conveying cylinder 5. Multiple front-to-back connecting rods 602 are installed between the inner side wall of the fixing frame 6 and the outer side wall of the conveying cylinder 5.

[0022] In this embodiment: When in use, the mixture containing water and river sand is introduced into the interior of the sand removal cylinder 1, so that the liquid forms a swirling flow in the sand removal cylinder 1. At the same time, the first motor 302 is started, so that the first bevel gear 303 rotates and drives the second bevel gear 304, the rotating cylinder 3 and multiple stirring blades 301 to rotate, which can accelerate the sedimentation of sand particles in the water into the sand storage cylinder 2, and perform preliminary separation of water flow and sand particles.

[0023] When cleaning the sand particles in the sand storage cylinder 2, the valve on the feed pipe 201 can be opened and the second motor 4 can be started. This causes the rotating rod 401 to drive the two scrapers 402 to rotate and remove the sand particles accumulated on the inner wall of the sand storage cylinder 2. This causes the sand particles to fall into the conveying cylinder 5 through the feed pipe 201 at an accelerated speed. The spiral conveying rod 502 rotates to transport the sand particles. During the transportation process, the residual water in the sand particles can be discharged through multiple water outlets 503 and the drain pipe 601. The separated sand particles are discharged from the discharge pipe 504, thereby further separating the sand particles from the water and effectively improving the water filtration efficiency of the river sand.

[0024] As a technical optimization of this utility model, the upper end face of the sand removal cylinder 1 is penetrated and a rotating cylinder 3 is installed through a mechanical seal. The bottom of the rotating cylinder 3 extends into the interior of the sand removal cylinder 1 and multiple stirring blades 301 are installed on the outer side wall.

[0025] In this embodiment: by causing the rotating cylinder 3 to drive multiple stirring blades 301 to rotate, the liquid generates swirling and axial eddies, which can accelerate the settling of sand particles in the water.

[0026] As a technical optimization of this utility model, a first motor 302 is installed on the upper end face of the sand removal cylinder 1, a first bevel gear 303 is installed at the output end of the first motor 302, and a second bevel gear 304 installed on the outer side wall of the first bevel gear 303 is meshed with the outer side wall of the rotating cylinder 3.

[0027] In this embodiment: by starting the first motor 302, the first bevel gear 303 rotates, driving the second bevel gear 304 to rotate, which in turn causes the second bevel gear 304 to drive the rotating cylinder 3 to rotate.

[0028] As a technical optimization of this utility model, the fixing frame 6 is semi-circular and the bottom is connected to a drain pipe 601.

[0029] In this embodiment, a drain pipe 601 is provided to facilitate the drainage of water from inside the fixed frame 6.

[0030] As a technical optimization of this utility model, the outer wall of the conveying cylinder 5 is connected to the discharge pipe 504 located on the right side of the fixed frame 6.

[0031] In this embodiment, the discharge pipe 504 is provided to facilitate the discharge of sand particles.

[0032] As a technical optimization of this utility model, the left side wall of the sand removal cylinder 1 is connected to a water inlet pipe 101, and the top of the rotating cylinder 3 is equipped with a water outlet pipe 305. The top of the rotating cylinder 3 and the water outlet pipe 305 are connected by mechanical seals, and the second motor 4 and the bottom end face of the sand storage cylinder 2 are connected by mechanical seals.

[0033] In this embodiment: the mixture of water and river sand is introduced into the sand removal cylinder 1 through the water inlet pipe 101. The water outlet pipe 305 is provided to facilitate the discharge of the separated water. The sealing performance is increased by mechanically sealing the rotating cylinder 3 with the water outlet pipe 305 and the bottom end face of the second motor 4 with the sand storage cylinder 2.

[0034] Working principle: First, when using this device, connect it to an external power source. Then, introduce a mixture of water and river sand into the sand removal cylinder 1, causing the liquid to swirl within the cylinder. Simultaneously, start the first motor 302, causing the first bevel gear 303 to rotate, which in turn drives the second bevel gear 304, the rotating cylinder 3, and multiple stirring blades 301 to rotate. This rotation induces swirling and axial eddies in the liquid, accelerating the sedimentation of sand particles in the sand storage cylinder 2. The separated water overflows through the rotating cylinder 3 to the outlet pipe 305 and is then discharged from the outlet pipe 305, emptying the sand storage cylinder 2. When cleaning the sand particles inside, the valve on the feed pipe 201 can be opened and the second motor 4 can be started, so that the rotating rod 401 drives the two scrapers 402 to rotate and remove the sand particles accumulated on the inner wall of the sand storage cylinder 2, and push the sand particles through the feed pipe 201 into the conveying cylinder 5. By starting the third motor 501, the screw conveyor 502 is rotated to convey the sand particles. During the conveying process, the residual water in the sand particles can be discharged through multiple water outlets 503 and fall into the fixed frame 6, and then be discharged from the drain pipe 601. The separated sand particles are discharged from the discharge pipe 504.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
