Description

Technical Field

[0001] This utility model relates to the field of screening machine technology, specifically a screening device for water-coated sand production. Background Technology

[0002] Water-based sand coating is a water-based environmentally friendly architectural coating made of acrylic emulsion, natural colored sand and additives. During the production process of water-based sand coating, a screening machine is needed to remove excessively large aggregates or impurities to ensure that the colored sand particles in the coating are uniform in size and reasonably distributed.

[0003] Existing patent application number: 202110126948.1 Screening device and screening method, including a screening platform and a screen structure. The screening platform has a mesh end face for preliminary screening of sand and gravel. An internal cavity with an opening facing downward is formed below the mesh end face. The screening platform is provided with a sand inlet channel connected to the cavity, which is used for direct input of sand and gravel into the cavity. The screen structure is set below the mesh end face and the sand inlet channel. The screen structure is used to screen the sand and gravel directly input into the cavity. The screen structure is also used to perform secondary screening of the sand and gravel after preliminary screening by the mesh end face.

[0004] The aforementioned patent describes the structural principle of existing screening machines. In practical applications, the outlet positions of fine and coarse materials in the screening machine are relatively fixed, making it inconvenient to adjust their relative orientation according to the on-site working environment. This may cause inconvenience to subsequent material collection. In addition, the coarse material outlet of the existing screening machine is difficult to adapt to materials of different particle sizes, causing materials to be discharged too early, affecting screening accuracy. Therefore, we propose a screening device for water-coated sand production to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a screening device for the production of water-coated sand, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a screening device for water-coated sand production, comprising an upper box, a feed bin, a coarse material inlet, a screen, a vibrating motor, a lower box, an orientation adjustment mechanism, and a diameter adjustment mechanism. The feed bin is connected to the top of the upper box. The coarse material inlet is centrally located on the front of the upper box. A screen is obliquely installed inside the upper box, with its leading edge fixed to the coarse material inlet. Vibrating motors are symmetrically installed on the left and right sides of the upper box. The bottom of the upper box is connected to the lower box via spring seats. The upper and lower housings are connected internally via a flexible connection. The bottom of the lower housing is equipped with an orientation adjustment mechanism, which includes a discharge hopper, a docking frame, a docking groove, and a support frame. The bottom of the lower housing is connected to the discharge hopper. A docking frame is welded to the top edge of the discharge hopper. A docking groove is provided around the bottom edge of the lower housing. The docking frame is movably inserted into the docking groove, allowing the lower housing and the discharge hopper to be movably connected. A support frame is screwed onto the bottom surface of the discharge hopper. A diameter adjustment mechanism is provided at the top edge of the coarse material outlet.

[0007] Preferably, the height of the docking frame is 20-40mm, and the depth of the docking groove matches the height of the docking frame.

[0008] Preferably, the left and right sidewalls of the discharge hopper are symmetrically equipped with buckles, and the bottom of the lower box is equipped with a hook, with the buckles and the hook engaging and fastening with the inside of the hook.

[0009] Preferably, a total of four hooks are provided, and the four hooks are equidistantly distributed on the four sides of the lower box.

[0010] Preferably, the diameter adjustment mechanism includes a connecting groove, a valve plate, and a positioning bolt. The connecting groove is provided on the top edge of the coarse material inlet. The left and right sides of the connecting groove are connected to the valve plate by guide rails. A positioning bolt is screwed into the screw hole in the middle of the front of the valve plate. The end of the positioning bolt passes through the valve plate and abuts against the connecting groove.

[0011] Preferably, the valve plate has an L-shaped longitudinal section, and the length of the valve plate matches the length of the coarse material inlet.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model features an orientation adjustment mechanism at the bottom of the lower housing. By disengaging the buckle and hook, and then removing the docking frame from the docking groove, the assembly angle between the discharge hopper and the lower housing can be readjusted. Finally, the buckle and hook are reconnected to complete the angle adjustment of the discharge hopper. This allows for adjustment of the relative orientation between the discharge hopper and the coarse material inlet according to the on-site working environment, facilitating subsequent material collection.

[0013] This invention features a diameter adjustment mechanism at the top edge of the coarse material inlet. When the valve plate is lowered, the diameter of the coarse material inlet decreases, reducing its throughput. When the valve plate is raised, the diameter of the coarse material inlet increases, improving its throughput. This allows for adaptive adjustment of the coarse material inlet according to the particle size of the material, preventing the material from being discharged too quickly from the coarse material inlet and extending the material's residence time on the screen, thereby ensuring the screening effect.

Detailed Implementation

[0016] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0017] Please see Figure 1 This utility model provides a screening device for water-coated sand production, including an upper box 1, a feed bin 2, a coarse material inlet 3, a screen 4, a vibrating motor 5, a lower box 6, an orientation adjustment mechanism 7, and a diameter adjustment mechanism 8. The feed bin 2 is connected to the top of the upper box 1. The coarse material inlet 3 is centrally located on the front of the upper box 1. The screen 4 is obliquely installed on the inner side of the upper box 1. The front edge of the screen 4 is connected and fixed to the coarse material inlet 3. The vibrating motors 5 are symmetrically installed on the left and right sides of the upper box 1. The bottom of the upper box 1 is elastically connected to the lower box 6 by a spring seat. The upper box 1 and the lower box 6 are internally connected. The orientation adjustment mechanism 7 is provided at the bottom of the lower box 6. The diameter adjustment mechanism 8 is provided at the top edge of the coarse material inlet 3.

[0018] Specifically, during the screening operation, the material is added into the upper box 1 through the feed hopper 2. At this time, the vibration motor 5 is powered on and applies vibration to the upper box 1, which promotes the stratification of the material on the screen 4. The material that meets the particle size is discharged downward into the lower box 6 through the screen 4 and finally discharged through the discharge hopper 71. The material that does not meet the particle size is guided by the screen 4 to the coarse material outlet 3 for discharge, thereby realizing the material sorting.

[0019] Please see Figure 2-4 This utility model provides a screening device for water-coated sand production. The orientation adjustment mechanism 7 includes a discharge hopper 71, a docking frame 72, a docking groove 73, and a support frame 74. The bottom of the lower box 6 is connected to the discharge hopper 71. The docking frame 72 is welded to the top edge of the discharge hopper 71. The docking groove 73 is arranged around the bottom edge of the lower box 6. The docking frame 72 is movably inserted into the inner side of the docking groove 73, so that the lower box 6 and the discharge hopper 71 are movably connected. The support frame 74 is screwed onto the bottom surface of the discharge hopper 71.

[0020] The height of the docking frame 72 is 20-40mm, and the depth of the docking groove 73 matches the height of the docking frame 72 to ensure the firmness of the insertion of the lower box 6 and the discharge hopper 71, making the structure stable and not easy to fall off.

[0021] To further explain, buckles 75 are symmetrically installed on the middle of the left and right side walls of the discharge hopper 71, and hooks 76 are installed on the middle of the bottom of the outer surface of the lower box 6. The buckles 75 and hooks 76 are interlocked and fastened on the inside, so that the lower box 6 and the discharge hopper 71 are fastened and fixed as one unit. The disassembly and assembly are simple and convenient for on-site adjustment. A total of four hooks 76 are provided, and the four hooks 76 are equally distributed on the four sides of the lower box 6 to ensure that the discharge hopper 71 can be fastened and fixed at all four turning angles.

[0022] Specifically, by setting an orientation adjustment mechanism 7 at the bottom of the lower housing 6, when adjusting the orientation, firstly, the connection between the buckle 75 and the hook 76 is released, and then the docking frame 72 is moved out from the docking groove 73, thereby separating the lower housing 6 from the discharge hopper 71. The assembly angle between the discharge hopper 71 and the lower housing 6 can then be readjusted. Finally, the buckle 75 and the hook 76 are reconnected to complete the angle adjustment of the discharge hopper 71. This allows the relative orientation of the discharge hopper 71 and the coarse material outlet 3 to be adjusted according to the on-site working environment, facilitating subsequent material collection.

[0023] Please see Figure 5 This utility model provides a screening device for water-coated sand production. The diameter adjustment mechanism 8 includes a connecting groove 81, a valve plate 82, and a positioning bolt 83. The top edge of the coarse material inlet 3 is provided with a connecting groove 81. The left and right sides of the connecting groove 81 are connected to the valve plate 82 by guide rails. The positioning bolt 83 is screwed into the screw hole in the middle of the front of the valve plate 82. The end of the positioning bolt 83 passes through the valve plate 82 and abuts against the connecting groove 81.

[0024] The valve plate 82 has an L-shaped longitudinal section, and the length of the valve plate 82 matches that of the coarse material inlet 3, thereby improving the material interception effect of the valve plate 82.

[0025] Specifically, by setting a diameter adjustment mechanism 8 at the top edge of the coarse material inlet 3, the positioning bolt 83 is first loosened to allow the valve plate 82 to resume free sliding inside the connecting groove 81. When the valve plate 82 is moved down for adjustment, the diameter of the coarse material inlet 3 decreases and the throughput is reduced. When the valve plate 82 is moved up for adjustment, the diameter of the coarse material inlet 3 increases and the throughput is improved. The coarse material inlet 3 can be adjusted adaptively according to the particle size of the material to prevent the material from being discharged from the coarse material inlet 3 too quickly and to prolong the residence time of the material on the screen 4, thereby ensuring the screening effect.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
