Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a combined rapid sand screening device. Background Technique
[0002] Sand is a fine-grained aggregate, usually used in the manufacture of concrete. Its delicate texture makes the concrete easier to construct, and it can fill the voids in the concrete, improving the density and strength of the concrete. Gravel is an aggregate with medium particle size, commonly used in road foundations and building foundations. Both are widely used in the field of building construction, and sand screening machines are essential.
[0003] The sand screening machine, also known as a dry land sand screening ship and a sand and stone separator, is a sand and stone separation device applicable to river channels, reservoirs, and coal yards. It is divided into drum type sand screening machines, water-washed drum type sand screening machines, vibrating screen type sand screening machines, etc. The sand screening machine imitates the working principle of manual sand screening using an inclined screen mesh, and adopts a horizontally placed rolling screen cylinder, so that the sand material is repeatedly tumbled and slid to be fully dispersed and separated; it is different from the situation where large and small materials are mutually pushed and buried caused by an inclined rolling screen, and the screening process is hasty; it is also different from the vibration and mixing of large and small materials of an inclined vibrating screen.
[0004] The inventor found the following problems in the prior art during the implementation of the present utility model: 1. The main function of the sand screening equipment is to separate gravel and sand. However, the sizes of the gravel are different, and the fixed-size filter screen cannot handle all situations. For example, if the material passing through is natural sand and gravel or artificial sand and gravel, if the filtration is improper, impurities will be generated, affecting the subsequent process; 2. The materials used in building construction are quantified according to the engineering quantity. Compared with continuous sand screening, batch sand screening cannot handle the situation of too large material volume, resulting in low efficiency, long time consumption, and increased labor costs. Content of the Utility Model
[0005] The purpose of the present utility model is to provide a combined rapid sand screening device to solve the problems of non-adjustable filter screen size and inability to work continuously mentioned in the above background technique. To achieve the above purpose, the present utility model provides the following technical solutions: A combined rapid sand screening device, including a sand screening component, a support A is movably connected to one side of the sand screening component, a feed pipe is inserted into the other side of the sand screening component, a support B is movably connected to the lower surface of the feed pipe, and a discharge inclined platform is fixedly connected to the lower side of the support A close to the sand screening component;
[0006] The sand screening component includes a rhombic filter screen, a baffle is movably connected to the front of the rhombic filter screen, a bolt penetrates through the lower part of the front of the baffle, an outer filter screen is clamped on the outer surface of the rhombic filter screen, a rotating shaft is fixedly connected to one side of the rhombic filter screen, a motor is rotatably connected to one side of the rotating shaft, and a handle is fixedly connected to one side of the outer filter screen.
[0007] Further preferably, a plug-in structure is formed between the sand screening assembly and the feed pipe.
[0008] Further preferably, a sliding structure is formed between the rhombic filter screen and the outer filter screen.
[0009] Further preferably, the outer filter screen forms a rotating structure with the motor through a rotating shaft.
[0010] Further preferably, the baffle forms a limiting structure with the rhombic filter screen through bolts.
[0011] Further preferably, the vertical center line of the sand screening assembly coincides with the vertical center line of the discharge inclined table.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] In the present utility model, in the field of construction, the separation of sand and stones is inevitable, and sand screening equipment is widely used. Considering different types of materials, such as natural sand and gravel and artificial sand and gravel, with different separation requirements and different size specifications of stones to be separated, a double-layer filter screen structure is now adopted. By horizontally adjusting the outer filter screen and misaligning the adjustment of the filter hole size, different materials and purification requirements can be met.
[0014] In the present utility model, the volume of materials in the field of construction is determined according to the engineering quantity. Screening sand in batches is not sufficient to cope with the situation of too large material volume. To cope with these two situations and improve the efficiency of sand and stone separation, save labor costs and time costs, a continuous feeding method is now adopted, and the function of continuous operation is realized by inserting the sand screening assembly and the feed pipe.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.
[0020] Please refer to Figures 1 to 3 , the present invention provides a technical solution: a combined rapid sand screening device, including a sand screening component 1, a support A 2 is movably connected to one side of the sand screening component 1, a feed pipe 3 is inserted into the other side of the sand screening component 1, a support B 4 is movably connected to the lower surface of the feed pipe 3, and a discharge inclined platform 5 is fixedly connected to the lower side of the support A 2 close to the sand screening component 1;
[0021] The sand screening component 1 includes a rhombic filter screen 101, a baffle 102 is movably connected to the front of the rhombic filter screen 101, a bolt 103 penetrates through the lower part of the front of the baffle 102, an outer filter screen 104 is clamped on the outer surface of the rhombic filter screen 101, a rotating shaft 105 is fixedly connected to one side of the rhombic filter screen 101, a motor 106 is rotatably connected to one side of the rotating shaft 105, and a handle 107 is fixedly connected to one side of the outer filter screen 104.
[0022] In this embodiment, as Figure 2 shown, a plug-in structure is formed between the sand screening component 1 and the feed pipe 3; the plug-in structure is convenient for disassembly, and the sand screening component 1 and the feed pipe 3 are more rotatable structures. Through the plug-in structure, the sand screening component 1 can rotate while the feed pipe 3 remains horizontal, which can realize the function of continuous feeding and is also convenient for disassembly.
[0023] In this embodiment, as Figure 2 shown, a sliding structure is formed between the rhombic filter screen 101 and the outer filter screen 104; the sliding structure in the horizontal direction is used to adjust the positional relationship between the rhombic filter screen 101 and the outer filter screen 104. By misaligning in the horizontal direction, the filter hole size can be changed to realize the function of filtering stones of different specifications and cope with various materials.
[0024] In this embodiment, as Figure 1 shown, the outer filter screen 104 forms a rotating structure with the motor 106 through the rotating shaft 105; the main functional structure of the sand screening component 1 is the main body of the sand screening device. The motor 106 drives the rotating shaft 105 and the outer filter screen 104 to rotate to generate centrifugal force. Through the centrifugal force, sand and stones are separated, and at the same time, the rhombic filter screen 101 and the outer filter screen 104 isolate the stones to realize the function of rapid sand screening.
[0025] In this embodiment, as Figure 2As shown, the baffle 102 and the diamond-shaped filter screen 101 form a limiting structure through bolts 103; the sand screening component 1 of the main body of the sand screening equipment has a limited capacity. For continuous long-term operation, the discharge port is required to unload stones to facilitate the maintenance and cleaning of the device. The function of unloading stones is completed by the baffle 102. At the same time, the horizontally connected bolts 103 are not easily detached during the rotation of the sand screening component 1. The structure is simple and convenient for manual operation.
[0026] In this embodiment, as Figure 3 shown, the vertical center line of the sand screening component 1 coincides with the vertical center line of the discharge inclined platform 5; the sand screening component 1 and the discharge inclined platform 5 are perpendicularly distributed. The vertical structure is beneficial to the collection of sand. The diamond-shaped filter screen 101 has filters on its four sides and five surfaces. When the sand screening component 1 rotates, most of the sand flows out in the vertical direction. At the same time, the curved inclined platform is beneficial to the collection and accumulation of sand, facilitating subsequent processes.
[0027] The usage method and advantages of the present utility model: When using this combined rapid sand screening equipment, the working process is as follows:
[0028] As Figure 1 、 Figure 2 and Figure 3 shown, first, the mixed material enters the sand screening component 1 through the feed pipe 3. The sand screening component 1 is driven to rotate by the motor 106 through the rotating shaft 105. The sand screening component 1 separates sand and stones through the centrifugal force generated by rotation and the filter screen. The stones remain in the sand screening component 1, and the sand falls onto the discharge inclined platform 5 through the filter screen, finally realizing the purification and accumulation of sand. At the same time, the outer filter screen 104 and the diamond-shaped filter screen 101 are connected by snap connection, and a handle 107 is fixed on one side. The size of the filter holes can be adjusted by horizontally adjusting the outer filter screen 104 relative to the diamond-shaped filter screen 101 through the handle 107. After continuous operation for a period of time, the baffle 102 can be opened to remove the stones and maintain the equipment for continuous, efficient, and rapid sand screening.
[0029] The above shows and describes the basic principles, main features, and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
