The disaggregation component 2 is arranged inside the equipment shell 1. The disaggregation component 2 is used to break up the clumped wet sand. The wet sand may aggregate together due to high humidity or adhesion between particles during the screening process, which will affect the screening effect.

[0028] like Figure 2 and Figure 3 As shown, two pulleys 25 are rotated below the support frame 24, and a belt 26 is sleeved between the outer surfaces of the two pulleys 25. The belt 26 plays a transmission role, so that the two pulleys 25 can achieve synchronous transmission. A straight rod 27 is fixed below one of the pulleys 25, and the pulley 25 drives the straight rod 27 to rotate through the transmission of the belt 26. A plurality of rubber sheets 28 are fixed to the outer surface of the straight rod 27 through a connecting rod. Holes are opened on the rubber sheets 28 to facilitate the passage of scattered sand, and when the rubber sheets 28 rotate with the straight rod 27, due to their own flexibility, they fit on the inner wall of the processing shell 21 to move the clumped sand and run over the sand. A motor 29 is fixed on the top of the processing shell 21, and one end of the output shaft of the motor 29 is fixed above one of the pulleys 25 for driving the pulley 25 to rotate.

[0029] like Figure 1 and Figure 2 As shown, an anti-sticking hole assembly 3 is arranged on the outside of the device shell 1, and the anti-sticking hole assembly 3 is used to help prevent wet sand from adhering to the net. The anti-sticking hole assembly 3 includes a heating shell 31 fixed to one side of the device shell 1 and two air outlet pipes 32 arranged inside the device shell 1. The two air outlet pipes 32 are respectively fixed to the opposite sides of the two baffles 8 on the primary screen 6. An air pump 33 is fixed on one side of the heating shell 31, and the air outlet end of the air pump 33 is connected to the heating shell 31, so that external air is drawn into the heating shell 31 for heating. Two electric heating wire groups 34 are arranged inside the heating shell 31. The electric heating wire group 34 The heating temperature is adjustable, and a control panel is provided on the device shell 1, which controls the motor 29, the vacuum pump 33, the internal motor 106, the small motor and other equipment, and is used to control the temperature of the heating wire group 34 and the heating wire 23. A connecting pipe 35 is fixed on the separated side of the two air outlet pipes 32, and one end of the two connecting pipes 35 is connected to the heating shell 31. A plurality of air outlet heads 36 are fixed on the opposite side of the two air outlet pipes 32, and the air outlet heads 36 face the primary screen 6. The evenly blown hot air reduces the humidity of the wet sand on the primary screen 6, which can help prevent the wet sand from adhering to the screen surface.

[0030] like Figure 1 , Figure 2 Figure 4 As shown, a supporting partition 4 is fixed inside the equipment shell 1, and a traction frame 5 is fixed above the supporting partition 4. A primary screen 6 is slidably installed on one side of the inner wall of the equipment shell 1, and one side of the primary screen 6 slides above the traction frame 5 to perform preliminary screening on the sand. A lower screen 7 is slidably installed on one side of the supporting partition 4. The lower screen 7 is arranged below the processing shell 21 to perform secondary screening on the dispersed sand. Two baffles 8 are fixed on the top of the primary screen 6 and the top of the lower screen 7. The baffle 8 can effectively prevent the sand from moving out of the mesh during screening and affecting the screening effect. A discharge port 9 is opened on one side of the equipment shell 1.

[0031] like Figure 4 As shown, both sides of the device shell 1 are provided with driving components 10, and the two driving components 10 respectively drive the primary screen 6 and the lower screen 7 to screen, and the driving components 10 are used to realize the sand screening work, and the driving components 10 include a hidden shell 101 fixed to one side of the device shell 1, two driving rods 102 rotating inside the device shell 1, and two hollow strips 103 arranged inside the device shell 1, one end of the two driving rods 102 is respectively penetrated in the two hollow strips 103, and the driving components 10 used to drive the primary screen 6 The two hollow strips 103 are fixed under the primary screen 6, and the two hollow strips 103 in the driving assembly 10 for driving the lower screen 7 are fixed under the lower screen 7. There are two limiting wheels 104 rotating inside the hidden shell 101, and a driving belt 105 is sleeved between the outsides of the two limiting wheels 104. The two limiting wheels 104 are respectively fixedly connected to one end of the two driving rods 102, and an inner motor 106 is fixed inside the hidden shell 101, and one end of the output shaft of the inner motor 106 is fixed to one of the limiting wheels 104.

[0032] like Figure 4 As shown, the internal motor 106 drives a limit wheel 104 connected to it to rotate, and the limit wheel 104 drives another limit wheel 104 to rotate through the driving belt 105, thereby driving the two driving rods 102 to rotate in the same direction at the same time. When the driving rod 102 rotates, it moves the hollow strip 103 back and forth through one end passing through the hollow strip 103, thereby driving the primary screen 6 and the lower screen 7 to shake and screen sand.

[0033] When in use, sand is put into the equipment shell 1, and the driving component 10 is started to drive the primary screen 6 and the lower screen 7 to shake back and forth to screen the sand. The fine sand passes through the primary screen 6 and falls out of the equipment shell 1, among which large granular impurities and agglomerated sand will be pulled into the processing shell 21 by the traction of the traction frame 5. After being heated by the heating wire 23, the water in the agglomerated wet sand evaporates rapidly, and the agglomerates will gradually disperse after the wet sand becomes dry. At the same time, the motor 29 is started to drive the pulley 25 connected thereto to rotate, and the pulley 25 drives another pulley 25 to rotate through the belt 26, thereby driving the straight rod 27 and the rubber sheet 28. The rubber sheet 28 stirs and breaks up the agglomerated sand inside the processing shell 21, and can evenly dry the wet sand, thereby increasing the dispersion rate of the wet sand. The dispersed sand falls on the lower screen 7 for screening, and the sieved granular impurities slide out of the equipment shell 1 through the discharge port 9, and the fine sand will fall out of the equipment shell 1.

[0034] When the primary screen 6 is screening, the anti-sticking hole assembly 3 is started, and the vacuum pump 33 draws air into the heating shell 31. The air heated by the electric heating wire group 34 will be sent to the air outlet pipe 32 through the connecting pipe 35, and will be blown evenly onto the primary screen 6 through the air outlet head 36, so as to reduce the humidity of the wet sand adhering to the mesh surface, thereby reducing the adhesion of the wet sand, which can help prevent the wet sand from adhering to the mesh surface and affecting the screening effect.

[0035] The above is only a preferred embodiment of the utility model, which is only illustrative and not restrictive. Those skilled in the art understand that many changes, modifications, and even equivalences can be made within the spirit and scope defined by the claims of the utility model, but they will all fall within the scope of protection of the utility model.
