Abstract
Description
Technical Field
[0001] This utility model relates to the field of sand separation technology, and in particular to a sand separation device for recycling waste mortar. Background Technology
[0002] Mortar is an indispensable cementing material in construction engineering. It is mainly composed of cementing materials, fine aggregates and water mixed in proportion. It is used in construction processes such as masonry, plastering and bonding. Mortar separation refers to the technology of separating and recovering the components in mortar or useful substances in waste mortar during construction or industrial processes.
[0003] Patent application publication number CN220939431U discloses a mortar solid-liquid separation and recycling device. It includes symmetrical fixed plates, a separation vessel fixed to the top of the fixed plates, a rotating rod rotatably mounted in the middle of the separation vessel, auger blades fixed to the rotating rod, a motor coaxially connected to the rotating rod, an inlet connected to the top of the separation vessel, an outlet connected to the bottom of the separation vessel, and a solid recovery bin placed below the outlet. When using this patent, the motor is turned on, driving the auger blades to rotate. Mortar is then poured into the inlet, and the auger blades continuously transport the mortar to the outlet. During this transport, water naturally falls from the liquid separation hole at the bottom of the separation vessel, while silt falls from the outlet into the solid recovery bin. However, this existing patent cannot classify the mortar particles. Unclassified sand particles are mixed together, leading to uneven structural strength and poor construction results when used in building materials. Furthermore, after solid-liquid separation, a large amount of moisture remains within the sand particles.
[0004] In view of the existing patents, there is a need for a sand separation device for waste mortar recycling that can classify mortar particles. Utility Model Content
[0005] In order to overcome the shortcomings of existing patents that cannot classify mortar particles, and that the use of unclassified sand particles in building materials will lead to uneven structural strength and poor construction results, and that a large amount of moisture still exists in the sand particles after solid-liquid separation, this utility model provides a sand separation device for waste mortar recycling that can classify mortar particles.
[0006] To address the aforementioned issues, this utility model employs the following technical solution: A sand separation device for waste mortar recycling, comprising a mounting frame, a drum screen, a discharge plate, a screw conveyor assembly, and a mortar inlet. The drum screen is fixedly connected to the mounting frame, and the discharge plate is fixedly connected to the drum screen. The screw conveyor assembly is mounted on the mounting frame, and the mortar inlet is provided on the drum screen. The device also includes a mounting bracket, a rectangular inlet, a guide frame, a hydrocyclone, an outlet, and a vibrating dewatering screen. The mounting bracket is fixedly connected to the mounting frame, and the rectangular inlet is provided on the mounting frame. A guide frame is provided on the rectangular inlet, a hydrocyclone is mounted on the rectangular inlet, and an outlet is provided on the hydrocyclone. The vibrating dewatering screen is mounted on the mounting bracket.
[0007] Optionally, it also includes a mounting plate, pads, and elastic elements. The mounting plate is fixedly connected inside the mounting bracket, and the same mounting plate is installed on the vibrating dewatering screen. The mounting plate is provided with pads, and four elastic elements are connected between two pads.
[0008] Optionally, it also includes an unloading rack, which is fixedly connected to the mounting bracket.
[0009] Optionally, it also includes a support frame, and the support frame is fixedly connected to the mounting bracket.
[0010] Optionally, the drum screen is inclined.
[0011] Optionally, the middle part of the unloading rack is a slope.
[0012] Compared with the prior art, the present invention has the following technical effects: 1. Fine particles and coarse particles are separated by the screen holes on the drum screen. Coarse sand particles are discharged from the central discharge port to the guide frame, while fine sand particles are discharged from the outer ring discharge port and enter the hydrocyclone to separate the sand particles and mud. The separated sand particles fall into the vibrating dewatering screen through the discharge port for dewatering treatment, thereby obtaining fine sand particles with lower moisture content, thus achieving the effect of particle classification, thereby ensuring that materials of each particle size can be properly processed.
[0013] 2. The vibration generated by the vibrating dewatering screen drives the mounting plate and soft pad on itself to vibrate. The mounting plate and soft pad absorb part of the vibration energy. At the same time, the mounting plate and soft pad compress the elastic element, which further absorbs the vibration, thereby reducing the risk of equipment resonance and extending its service life.

Detailed Implementation
[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.
[0019] Example 1: A sand separation device for waste mortar recycling, see reference. Figure 1 and Figure 2 As shown, the system includes a mounting frame 1, a drum screen 2, a discharge plate 3, a screw conveyor assembly 4, and a mortar inlet 5. The drum screen 2 is fixedly connected to the center of the mounting frame 1. The discharge plate 3 is fixedly connected to the drum screen 2. The cross-section of the discharge plate 3 and the drum screen 2 is annular, dividing it into a central and an outer ring discharge port. The screw conveyor assembly 4 is mounted on the mounting frame 1. The screw conveyor assembly 4 consists of a connecting frame, a drive motor, and screw conveyor blades. The connecting frame is fixedly connected to the left side of the mounting frame 1. The drive motor is mounted on the connecting frame, and the screw conveyor blades are mounted on the output shaft of the drive motor and located inside the drum screen 2. The drum screen 2 is equipped with a mortar inlet 5. The device includes a mounting bracket 6, a rectangular feed inlet 7, a guide frame 701, a hydrocyclone 8, a discharge outlet 9, and a vibrating dewatering screen 10. The mounting bracket 6 is welded to the bottom of the mounting bracket 1. A rectangular feed inlet 7 is located on the lower right side of the mounting bracket 1 and is connected to the outer ring discharge outlet 9. A guide frame 701 is located on the right side of the rectangular feed inlet 7 and is connected to the central discharge outlet 9. A hydrocyclone 8 is bolted to the bottom of the rectangular feed inlet 7 and passes through the mounting bracket 6. A discharge outlet 9 is located at the end of the hydrocyclone 8. A vibrating dewatering screen 10 is installed at the lower part of the mounting bracket 6 and is located below the discharge outlet 9.
[0020] See Figure 1 As shown, it also includes a support frame 15, and the support frame 15 is fixedly connected between the mounting frame 1 and the left side of the mounting bracket 6.
[0021] See Figure 1 As shown, the drum screen 2 is in an inclined state.
[0022] When this device is needed, waste mortar is first added into the drum screen 2 through the mortar inlet 5. Then, the screw conveyor blades of the screw conveyor assembly 4 are started to transport the waste mortar. The fine particles and coarse particles are separated through the screen holes on the drum screen 2. The coarse sand particles are discharged from the central outlet 9 to the guide frame 701, while the fine sand particles are discharged from the outer ring outlet 9 and enter the hydrocyclone 8. The hydrocyclone 8 uses centrifugal force to further separate the sand particles and slurry. The separated sand particles fall into the vibrating dewatering screen 10 through the outlet 9. The vibrating dewatering screen 10 further dewaters the fine sand particles, thereby obtaining fine sand particles with lower moisture content, thus achieving the effect of particle grading and ensuring that materials of each particle size can be properly treated.
[0023] Example 2: Based on Example 1, refer to Figure 3 As shown, it also includes a mounting plate 11, a soft pad 12, and an elastic element 13. The mounting plate 11 is installed at the bottom of the mounting bracket 6 by welding. The same mounting plate 11 is installed at the bottom of the vibrating dewatering screen 10. The soft pad 12 is provided on the inner side of the mounting plate 11. Four elastic elements 13 are connected between the two soft pads 12. The elastic elements 13 are damping springs.
[0024] See Figure 1 As shown, it also includes a discharge rack 14. The discharge rack 14 is fixedly connected to the right side of the mounting bracket 6, and the discharge rack 14 is connected to the vibrating dewatering screen 10.
[0025] See Figure 1 As shown, the middle part of the unloading rack 14 is an inclined surface.
[0026] When the vibrating dewatering screen 10 is running, the vibrating dewatering screen 10 generates vibration, which drives the mounting plate 11 and the soft pad 12 on its own to vibrate. The mounting plate 11 and the soft pad 12 absorb part of the vibration energy. At the same time, the mounting plate 11 and the soft pad 12 squeeze the elastic element 13, so that the elastic element 13 further absorbs the vibration, thereby reducing the risk of equipment resonance and extending the service life. When the screen body removes the surface moisture of the sand particles by high-frequency vibration, the separated water is discharged through the gap of the vibrating dewatering screen 10, and the dried sand particles are collected along the unloading frame 14.
[0027] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
