[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 3 As shown, a water-coated sand granulator includes a shell 1. A mixing chamber 101 and a screening chamber 103 are connected vertically within the shell 1. A mixing assembly is installed in the mixing chamber 101. A water inlet 104, a feed inlet 105, and a discharge outlet 106 are respectively provided on the upper and lower sides of the shell 1. A screen cage 6 is installed in the screening chamber 103. The upper and lower sides of the screen cage 6 are rotatably connected to the upper and lower sides of the screening chamber 103 via bearings. The mixing chamber 101 is internally connected to the screen cage 6. A screen is bolted to the circumferential side of the screen cage 6. The screen mesh has a mesh diameter that can be changed according to production needs. A rotating motor 7 is bolted to the lower side of the housing 1. The output shaft of the rotating motor 7 passes through the housing 1 and is connected to the screen cage 6. A conical platform 601 is integrally formed on the lower side of the inner cavity of the screen cage 6. A valve chamber 102 is provided between the screening chamber 103 and the stirring chamber 101. A first solenoid valve 4 is provided in the valve chamber 102 to prevent the screening chamber 103 from communicating with the stirring chamber 101. A cleaning component for cleaning the screen cage 6 is provided in the screening chamber 103.

[0020] The feed inlet 105 is equipped with a feeding component for primary screening of raw materials.

[0021] During use, the operator pours the raw materials into the feeding assembly for the first screening. After the first screening, the raw materials pass through the feed inlet 105 into the mixing chamber 101. At this time, under the action of the first solenoid valve 4, the raw materials in the mixing chamber 101 cannot enter the screening chamber 103. After the raw materials enter the mixing chamber 101, the operator adds water to the mixing chamber 101 through the water inlet 104 and uses the mixing assembly to fully mix the raw materials and water. After the materials in the mixing chamber 101 are mixed, the operator opens the first solenoid valve 4 to allow the materials in the mixing chamber 101 to mix. The material enters the screen cage 6. Then, the operator controls the rotating motor 7 to drive the screen cage 6 to rotate. Under the action of centrifugal force, the screen cage 6 performs secondary filtration on the mixed material. Qualified material can pass through the screen under the action of centrifugal force and enter the outside of the screen cage 6. Unqualified material will be blocked by the filter screen 14 and remain in the screen cage 6, thus realizing secondary filtration of water-coated sand and improving the quality of water-coated sand. After the production is completed, the operator can discharge the unqualified material in the screen cage 6 with the action of the cleaning component to ensure the reliability of the screen cage 6 during use.

[0022] In this embodiment, the cleaning assembly includes a protective shell 9 bolted to the circumferential side of the screening chamber 103. The inner side of the protective shell 9 is sealed to a cleaning shell 10 rotatably connected to the housing 1 via a bearing. The protective shell 9 has a plurality of water spray nozzles 901 arranged in a circular array on its side. The cleaning shell 10 has a plurality of nozzles 11 arranged in a circular array on its side. The nozzles 11 can rotate with the cleaning shell 10 and communicate with the water spray nozzles 901. The outer side of the cleaning shell 10 is fitted with a water pipe communicating with the inner cavity of the cleaning shell 10 via bolts and connecting columns. The water spray nozzles 901 and the nozzles 11 are all facing the screen cage 6. The lower side of the screen cage 6 has a plurality of discharge holes 602 communicating with the lower side of the housing 1. The lower side of the housing 1 is fitted with a sealing ring plate 8 that can close the discharge holes 602 via bolts.

[0023] When cleaning the screen cage 6, the workers remove the sealing ring plate 8 to connect the discharge hole 602 with the lower side of the shell 1. Then, the workers rotate the cleaning shell 10 to connect the nozzle 11 with the water spray nozzle 901, and supply water to the cleaning shell 10 through the water pipe. The water flow in the cleaning shell 10 can spray out along the nozzle 11 and through the water spray nozzle 901 to the outer surface of the screen cage 6, spraying the material on the screen cage 6 into the screen cage 6. The water flow and unqualified materials in the screen cage 6 can be discharged to the outside through the discharge hole 602 to ensure the reliability of the screen cage 6 during use. After cleaning, the workers rotate the cleaning shell 10 to disconnect the nozzle 11 from the water spray nozzle 901 to prevent the material in the screening chamber 103 from clogging the nozzle 11. At the same time, the sealing ring plate 8 is used again to seal the discharge hole 602 to prevent the material in the screen cage 6 from flowing out.

[0024] In this embodiment, a sealing gasket 12 is provided on the side of the cleaning shell 10, which contacts the inner side of the protective shell 9. In use, the sealing gasket 12 further improves the sealing between the cleaning shell 10 and the protective shell 9, preventing the material in the screening chamber 103 from getting stuck between the cleaning shell 10 and the protective shell 9 and affecting the rotation of the cleaning shell 10.

[0025] In this embodiment, the feeding assembly includes a feeding frame 13 bolted to the upper side of the housing 1 and a filter screen 14 bolted inside the feeding frame 13. The feeding frame 13 communicates with the feeding port 105. The filter screen 14 is inclined downward from left to right. A cleaning port 131 is provided on the right side of the feeding frame 13. The lower side of the cleaning port 131 is flush with the upper side of the right end of the filter screen 14. A sealing plate 15 is bolted to the right side of the feeding frame 13 to close the cleaning port 131. A sealing plate 15 located below the sealing plate 15 is bolted to the upper side of the housing 1. In use, the staff pours the raw materials into the feed box 13. The filter screen 14 filters the raw materials once under the action of gravity. Unqualified raw materials will stay on the upper side of the filter screen 14 and roll down to the cleaning port 131 under the action of gravity. When it is necessary to clean the raw materials above the filter screen 14, the staff can remove the blocking plate 15. The material above the filter screen 14 can fall into the collection box 16 through the cleaning port 131 under the action of gravity, which makes it easier for the staff to collect the material above the filter screen 14.

[0026] In this embodiment, the stirring assembly includes a stirring shaft 3 rotatably connected to the upper side of the stirring chamber 101 via a bearing and a stirring motor 2 bolted to the upper side of the housing 1. The output shaft of the stirring motor 2 passes through the housing 1 and is connected to the stirring shaft 3. In use, the stirring motor 2 can drive the stirring shaft 3 to rotate, thereby realizing the stirring of the material in the stirring chamber 101.

[0027] In this embodiment, the discharge port 106 is equipped with a second solenoid valve 5 through threads and a sealing gasket. During use, the operator can control the discharge of material from the screening chamber 103 through the second solenoid valve 5, which improves the convenience of the operator in controlling the discharge of material.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
