Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings and embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.

Through the research of researchers, the following results are found: river sand needs to be separated after being cleaned, and at present, a filter screen separation mode is mainly adopted, so that the mode not only needs great labor cost, but also can cause the discontinuity of the river sand cleaning process, and the cleaning efficiency of the river sand is reduced. The applicant finds that the muddy water has certain fluidity, so that the muddy water starts from the characteristic, the washed river sand is lifted upwards, and the muddy water flows downwards due to gravity, so that the separation of the river sand and the muddy water is realized.

As shown in fig. 1 and 2, the present invention provides a device for filtering water from river sand, which comprises a frame 10, a water filtering cylinder 20, a lifting assembly 30 and a driving assembly 40.

Specifically, the water filtering cylinder 20 is arranged obliquely, the side wall of the water filtering cylinder 20 is welded and fixed with the frame 10, a feed port 21 is formed in one end, close to the bottom, of the side wall of the water filtering cylinder 20, the feed port 21 is inclined up and down, and a feed hopper 50 is arranged on the feed port 21. The end of the side wall of the water filtering cylinder body 20 close to the top is provided with a discharge pipe 60 downwards, and the discharge pipe 60 is communicated with the inside of the water filtering cylinder body 20.

The lifting assembly 30 in this embodiment is disposed in the water filtering cylinder 20, the lifting assembly 30 is fixedly connected with the output end of the driving assembly 40, the driving assembly 40 drives the lifting assembly 30 to move so that the lifting assembly 30 lifts the river sand upwards, and in the process of rising the river sand, mud and water mixed in the river sand flow downwards to separate the river sand from the mud and water. Specifically, the lifting assembly 30 includes a rotating shaft 31 and a helical blade 32. Wherein, the rotating shaft 31 is inserted into the water filtering cylinder 20 along the length direction of the water filtering cylinder 20; meanwhile, the top end of the rotating shaft 31 is fixedly connected with the output end of the driving assembly 40. The helical blade 32 is wound around the rotating shaft 31 along the length direction of the rotating shaft 31; the helical blade 32 and the rotating shaft 31 are welded and fixed.

Referring to fig. 3, the driving assembly 40 in the present embodiment includes a driving motor 41 and a speed reducer 42, and the driving assembly 40 is fixedly connected to the top of the water filtering cylinder 20. Specifically, the housing of the driving motor 41 is fixedly connected to the housing of the speed reducer 42, and the output shaft of the driving motor 41 is fixedly connected to the input end of the speed reducer 42. The housing of the speed reducer 42 is fixedly connected to the top end of the water filtering cylinder 20, and the output end of the speed reducer 42 extends from the top of the water filtering cylinder 20 to the inside of the water filtering cylinder 20 along the length direction of the water filtering cylinder 20 and is fixedly connected to the top end of the rotating shaft 31. The driving motor 41 drives the rotating shaft 31 to rotate after being decelerated by the speed reducer 42, the spiral blade 32 rotates along with the rotating shaft to lift the river sand upwards, and the mixture and mud water in the river sand flow downwards in the process, so that the separation of the river sand and the mud water is realized. The rotating speed of the rotating shaft 31 can be reduced by arranging the speed reducer 42 between the driving motor 41 and the rotating shaft 31, and the situation that the river sand is lifted too fast due to too fast rotating speed of the rotating shaft 31 so that muddy water mixed with the river sand is not separated in time is avoided.

In the process of separating river sand from mud water, the muddy concentration in the water filtering cylinder body 20 is higher and higher, which easily causes the muddy deposition in the water filtering cylinder body 20. To solve this problem, in a further embodiment, a drain pipe 70 is fixed to an end of the side wall of the filtering cylinder 20 near the bottom, and the drain pipe 70 is communicated with the inside of the filtering cylinder 20. Meanwhile, a water valve 71 is provided on the drain pipe 70. When water needs to be drained, the water valve 71 is opened, and muddy water in the water filtering cylinder body 20 is drained from the drain pipe 70, so that muddy sediment in the water filtering cylinder body 20 is avoided, and the cleaning difficulty of the water filtering cylinder body 20 is reduced.

Since the length of the rotating shaft 31 is long, the end of the rotating shaft 31 remote from the driving assembly 40 is easily eccentrically offset during the rotation of the rotating shaft 31, resulting in deformation of the rotating shaft 31. Therefore, in a further embodiment, in conjunction with fig. 4, a support base 80 is fixed on the inner wall of the bottom of the water filtering cylinder 20, the support base 80 extends a support sleeve 81 into the water filtering cylinder 20, the support sleeve 81 and the water filtering cylinder 20 are coaxially arranged, and one end of the rotating shaft 31 far away from the driving assembly 40 is inserted into the support sleeve 81. The rotating shaft 31 is supported by the support sleeve 81, so that the coaxiality of the rotating shaft 31 in the rotating process is ensured, and the deformation of the rotating shaft 31 is reduced.

After the river sand and mud-water separation process is finished, sediment can be deposited on the water filtering cylinder body 20 and the spiral blade 32, and sediment deposition and hardening agglomeration can be caused if the sediment is not cleaned in time. To prevent this, an inlet pipe 90 is opened upward at an end of the side wall of the filtering cylinder 20 near the top, and the inlet pipe 90 communicates with the inside of the filtering cylinder 20. Water is injected into the water filtering cylinder 20 through the water inlet pipe 90, silt on the water filtering cylinder 20 and the helical blades 32 is washed clean through continuous washing of water, and the washed muddy water is discharged through the drain pipe 70 at the bottom of the water filtering cylinder 20, so that the sediment deposition is avoided.

The working principle is as follows: after the river sand is cleaned, the mud in the river sand is dissolved in water, and the mixture of the river sand and the mud water is injected into the water filtering pipe body through the feeding funnel 50; the driving motor 41 drives the rotating shaft 31 to rotate through the speed reducer 42, the spiral blade 32 rotates to lift the river sand upwards, muddy water in the mixed river sand flows downwards due to the influence of self gravity in the river sand lifting process so as to be separated from the river sand, and the separated river sand is discharged from the discharge pipe 60 under the rotation of the spiral blade 32. The river sand and mud and water are separated in a mechanical mode, so that the investment of labor cost can be greatly reduced; meanwhile, in the process of separating the river sand from the mud water, the mixture of the river sand and the mud water can be continuously injected into the water filtering cylinder body 20 from the feeding funnel 50, so that the cleaning process of the river sand is not influenced, the continuity of the cleaning of the river sand is ensured, and the cleaning efficiency of the river sand is further ensured.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
