Description

Technical Field

[0001] This utility model relates to the technical field of cement mortar screening, and in particular to a cement mortar vibrating screen. Background Technology

[0002] In the field of building materials production, cement mortar is a key material that is widely used in many construction processes such as wall construction, floor paving, and waterproofing. Cement mortar is mainly composed of cement, fine aggregate and water, while cement-mixed mortar is made by adding lime to cement mortar. The two have different properties and uses due to differences in composition.

[0003] In the production process of cement mortar, the particle size of fine aggregate has a significant impact on product quality and production cost. Fine aggregate with different particle sizes will cause cement mortar to exhibit different properties. For example, if the fine aggregate particles are too large, the workability of the cement mortar may be reduced, affecting construction operations; while if the particles are too small, the amount of cement used may be increased, thereby increasing production costs. Therefore, accurate screening of fine aggregate particles has become a key link in ensuring the quality of cement mortar and controlling production costs.

[0004] In related technologies, fine aggregate particles tend to accumulate when sliding on a screen plate. As the screening operation continues, more and more particles accumulate, making it difficult for the particles at the bottom to be fully screened, resulting in low screening efficiency and failing to meet the needs of large-scale production. In addition, fine aggregate particles are also prone to uneven distribution on the screen plate, with some areas having excessively concentrated particles and others being under-screened, affecting the screening effect of the screen on fine aggregate particles. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, this utility model proposes a cement mortar vibrating screen that can achieve efficient vibration and precise grading of materials, optimize particle turning, facilitate material guiding and collection, and effectively improve the efficiency, accuracy and practicality of cement mortar fine aggregate screening.

[0007] To achieve the above objectives, this utility model proposes a cement mortar vibrating screen, comprising a base, a vibrating mechanism, a vibrating screen mechanism, and a screening and guiding mechanism. The vibrating mechanism is disposed above the base and includes multiple sliding seats, multiple upper sliding columns, a support plate, a bracket, an elliptical disk, and a motor. The sliding seats are fixedly disposed above the base in a matrix arrangement, and the upper sliding columns are slidably connected to the sliding seats. The support plate is fixedly disposed above the multiple upper sliding columns, and the bracket is fixed to the bottom of the support plate. The elliptical disk is rotatably disposed on the bracket, and the motor is disposed above the base, with its output end connected to a turntable, which is slidably connected to the elliptical disk. The vibrating screen mechanism is disposed above the support plate. The screening and guiding mechanism is fixedly disposed above the base and adapted to the vibrating screen mechanism, and is used to guide and collect the screened material.

[0008] This utility model of a cement mortar vibrating screen can achieve efficient vibration and precise grading of materials, optimize particle tumbling, facilitate material guiding and collection, and effectively improve the efficiency, accuracy and practicality of cement mortar fine aggregate screening.

[0009] In addition, the cement mortar vibrating screen proposed in this application may also have the following additional technical features:

[0010] Specifically, the vibrating screen mechanism includes multiple slot seats, multiple springs, multiple feet, multiple side frames, and a vibrating screen assembly. The slot seats are fixedly arranged in a matrix above the support plate, and the springs are arranged in the slot seats. The feet are slidably connected to the slot seats, and the upper ends of the springs are connected to the feet. The side frames are fixedly arranged above the feet, and the vibrating screen assembly is arranged on the multiple side frames.

[0011] Specifically, the vibrating screen assembly includes multiple screen support frames, which are arranged vertically in parallel between multiple side frames; there are three screen support frames, which are inclined to the lower left; the upper and middle screen support frames are provided with vibrating screen plates, and the lower screen support frame is provided with a flat plate; the aperture of the upper vibrating screen plate is larger than the aperture of the lower vibrating screen plate.

[0012] Specifically, multiple bottom arc frames are uniformly fixed above the vibrating screen plate.

[0013] Specifically, sliding members are slidably connected to the sides of the upper and middle screen support frames, and a lever is provided between the corresponding sliding members; the lever includes a lever frame disposed between the corresponding sliding members, and a lever post is disposed within the lever frame; an electric slide rail is fixedly disposed on one side of the middle screen support frame, and an electric slide block is slidably connected to the electric slide rail; a connecting frame is provided on the electric slide block, and the connecting frame is fixedly connected to two corresponding sliding members on the same side. When the electric slide block slides on the electric slide rail, it drives the sliding members to slide on the side of the screen support frame through the connecting frame.

[0014] Specifically, the screening and guiding mechanism includes a support frame and multiple guide frames. The support frame is fixedly mounted on the base. The guide frames are evenly arranged in the vertical direction of the support frame. The multiple guide frames are inclined to the lower left. The positions of the multiple guide frames correspond to the positions of the multiple screen support frames, and the corresponding guide frames are located below the screen support frames. A partition is detachably mounted on the guide frame.

[0015] Compared with the prior art, the beneficial effects of this application are as follows:

[0016] 1. High-efficiency vibrating screen: Through the unique structural design of the vibrating mechanism, the motor drives the turntable to rotate, which in turn drives the specially designed elliptical disc to rotate, causing the support to move back and forth. The upper sliding column slides continuously on the lower sliding seat, and the support plate vibrates up and down. During this process, the spring in the slot seat deforms continuously, driving the vibrating screen assembly on the side frame to vibrate continuously. Compared with traditional screening equipment, this vibration method allows the fine aggregate particles in cement mortar to have more full contact with the screen, effectively avoiding particle accumulation and greatly improving screening efficiency.

[0017] 2. Precise Grading and Screening: The vibrating screen assembly is equipped with vibrating screen plates of different aperture sizes, and the screen support frame is tilted to the lower left, with the upper vibrating screen plate having a larger aperture than the lower one. During vibration, fine aggregate particles can pass through the screen plates of different aperture sizes sequentially according to their particle size, achieving precise grading and screening. This meets the stringent requirements for fine aggregates of different particle sizes in cement mortar production and improves product quality.

[0018] 3. Optimized Particle Turning: Multiple bottom arc frames evenly fixed above the vibrating screen plate can intercept and turn the downward-moving mortar particles, preventing the formation of a particle accumulation layer on the screen plate. This allows fine aggregate particles to be more evenly distributed on the screen mesh, increasing the contact opportunity between particles and the screen. Simultaneously, the electric slide block slides on the electric slide rail, driving the connecting frame and sliding parts to slide together. This causes the turning frame to reciprocate and turn the fine aggregate particles of the vibrating mortar in the upper and middle screen support frames, further optimizing the particle turning effect and improving screening accuracy.

[0019] 4. Convenient Material Guiding and Collection: Multiple downward-sloping guide frames are evenly arranged on the support frame of the screening and guiding mechanism, corresponding to and located below the screen support frame. The screened fine aggregate particles can slide smoothly down the guide frames under gravity, facilitating collection. Removable partitions on the guide frames allow for adjustment of the guiding path and collection area according to actual needs, enhancing the practicality and flexibility of the equipment.

[0028] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0029] The cement mortar vibrating screen of this utility model embodiment will be described below with reference to the accompanying drawings.

[0030] like Figures 1-5 As shown, the cement mortar vibrating screen of this utility model embodiment may include a base 1, a vibration mechanism, a vibrating screen mechanism, and a screening and guiding mechanism.

[0031] The vibration mechanism is located above the base 1 and includes multiple sliding seats 2, multiple upper sliding columns 3, support plates 4, brackets 5, elliptical disks 6, and motors 7.

[0032] Among them, the sliding seat 2 is fixedly installed above the base 1 and distributed in a matrix. The upper sliding column 3 is slidably connected to the sliding seat 2. The support plate 4 is fixedly installed above multiple upper sliding columns 3. The bracket 5 is fixed at the bottom of the support plate 4. The elliptical disk 6 is rotatably installed on the bracket 5. The motor 7 is installed above the base 1, and the output end of the motor 7 is connected to the turntable 8. The turntable 8 is slidably connected to the elliptical disk 6.

[0033] The vibrating screen mechanism is set above the support plate 4, and the screening and guiding mechanism is fixedly set above the base 1 and adapted to the vibrating screen mechanism. The screening and guiding mechanism is used to guide and collect the screened material.

[0034] In one embodiment of the present invention, the vibrating screen mechanism may include multiple slot seats 9, multiple springs 11, multiple foot seats 10, multiple side frames 12, and a vibrating screen assembly.

[0035] Among them, the slot seat 9 is fixedly installed above the support plate 4 in a matrix, the spring 11 is installed in the slot seat 9, the foot seat 10 is slidably connected to the slot seat 9, and the upper end of the spring 11 is connected to the foot seat 10. The side frame 12 is fixedly installed above the foot seat 10, and the vibrating screen assembly is installed on multiple side frames 12.

[0036] Furthermore, the vibrating screen assembly may include multiple screen support frames 13, which are vertically parallel to each other among multiple side frames 12. There are three screen support frames 13, and they are inclined downwards to the left (e.g., Figure 1 As shown, the upper and middle screen support frames 13 are provided with vibrating screen plates 14, and the lower screen support frame 13 is provided with a flat plate 15. The aperture of the upper vibrating screen plate 14 is larger than that of the lower vibrating screen plate 14.

[0037] Furthermore, multiple bottom arc frames 16 are uniformly fixed above the vibrating screen plate 14.

[0038] Specifically, the vibration mechanism utilizes motor 7 for power. The rotational motion output by motor 7 is transmitted to elliptical disk 6 via turntable 8. Due to the special shape of elliptical disk 6, it will generate eccentric motion during rotation, continuously pushing and releasing support 5, thereby converting the rotational motion into the up-and-down reciprocating motion of support 5. Support 5 is fixedly connected to support plate 4, driving support plate 4 to vibrate up and down. The sliding connection structure between upper sliding column 3 and lower sliding seat 2 ensures the stability of support plate 4 vibration on the one hand, and effectively disperses the vibration force on the other hand, reducing the wear of equipment parts. At the same time, the buffer structure composed of slot seat 9, spring 11 and foot seat 10 not only enhances the vibration effect, but also plays a buffering role during equipment vibration, protecting other parts of the equipment and improving the stability of equipment operation.

[0039] In one embodiment of this utility model, slide members 17 are slidably connected to the sides of the upper and middle screen support frames 13, and a lever is provided between the corresponding slide members 17. The lever includes a lever frame 18 disposed between the corresponding slide members 17, and a lever post 19 is disposed in the lever frame 18. An electric slide rail 20 is fixedly disposed on one side of the middle screen support frame 13, and an electric slide seat 21 is slidably connected to the electric slide rail 20. A connecting frame 22 is disposed on the electric slide seat 21, and the connecting frame 22 is fixedly connected to two corresponding slide members 17 on the same side. When the electric slide seat 21 slides on the electric slide rail 20, it drives the slide members 17 to slide on the side of the screen support frame 13 through the connecting frame 22.

[0040] Specifically, the vibrating screen assembly adopts a multi-layer screen plate design. The apertures of the vibrating screen plates 14 on the upper and middle screen support frames 13 are different, and the screen support frames 13 are tilted to the lower left. When the vibrating screen assembly vibrates, the fine aggregate particles in the cement mortar move continuously under the action of vibration. Particles with a diameter smaller than the aperture of the upper vibrating screen plate 14 pass through the screen plate under the action of vibration and gravity and continue to be screened downwards. Particles with a diameter larger than the aperture of the upper vibrating screen plate 14 remain in the upper screen support frame 13. In this way, the initial separation of fine aggregate particles of different sizes is achieved. The bottom arc frame 16 and the deflector frame increase the degree of particle turning and mixing, so that the particles can contact the screen plate more fully, avoid particle accumulation, and improve the screening accuracy and efficiency.

[0041] In one embodiment of the present invention, the screening and guiding mechanism may include a support frame 23 and a plurality of guide frames 24. The support frame 23 is fixedly mounted on the base 1, and the guide frames 24 are evenly arranged in the vertical direction of the support frame 23. The plurality of guide frames 24 are inclined to the lower left and the plurality of guide frames 24 correspond to the positions of the plurality of screen support frames 13, and the corresponding guide frames 24 are located below the screen support frames 13. A partition 25 is detachably mounted on the guide frame 24.

[0042] Specifically, the screening and guiding mechanism utilizes gravity to guide and collect materials. The guide frame 24 corresponds to and is located below the screen support frame 13, and is tilted to the lower left. Under the action of gravity, the screened fine aggregate particles naturally slide down the screen support frame 13 onto the guide frame 24. The guide frame 24 has a detachable partition 25, which can adjust the guiding path and collection area according to actual needs, realizing the classified collection of materials of different particle sizes, which facilitates subsequent processing and use of the materials.

[0043] Specifically, the overall workflow and principle of this utility model are as follows:

[0044] Material screening: After the equipment is debugged, start the motor 7. The motor 7 drives the turntable 8 to start rotating. During the rotation of the turntable 8, through the sliding connection with the elliptical disk 6, the elliptical disk 6 rotates around its central axis. Due to the special shape of the elliptical disk 6, it will continuously push the support 5 when rotating. The support 5 is fixed at the bottom of the support plate 4, which in turn drives the support plate 4 to vibrate up and down. The vibration of the support plate 4 is transmitted to the upper sliding column 3. The upper sliding column 3 slides continuously on the lower sliding seat 2, ensuring the stability and continuity of the vibration.

[0045] The vibration of the support plate 4 is transmitted to the spring 11 through the groove seat 9. The spring 11 is continuously compressed and extended, causing the foot seat 10 to slide up and down in the groove seat 9. The side frame 12 above the foot seat 10 vibrates accordingly, and the vibrating screen assembly installed on the side frame 12 also begins to vibrate. The cement mortar to be screened is placed on the upper vibrating screen plate 14. Under the vibration of the vibrating screen assembly, the fine aggregate particles in the cement mortar begin to move. The bottom arc frame 16 above the vibrating screen plate 14 blocks and turns the mortar particles moving downward, preventing the particles from accumulating and making the particles more evenly distributed on the screen plate, increasing the contact opportunity between the particles and the screen plate.

[0046] Simultaneously, the electric slide rail 20 is activated, and the electric slide block 21 slides back and forth on the electric slide rail 20 according to the set program. The electric slide block 21 drives the sliding component 17 to slide on the side of the screen support frame 13 through the connecting frame 22. The sliding component 17 drives the lever frame to move. The lever column 19 on the lever frame reciprocates to turn the mortar fine aggregate particles in the upper and middle screen support frames 13, further optimizing the particle screening effect. Particles with a diameter smaller than the aperture of the upper vibrating screen plate 14 pass through the screen plate and fall onto the middle vibrating screen plate 14 for further screening; particles with a diameter smaller than the aperture of the middle vibrating screen plate 14 pass through the middle screen plate and fall onto the lower plate 15; while particles with a diameter larger than the aperture of the middle vibrating screen plate 14 remain in the middle screen support frame 13, realizing the screening of fine aggregate particles of different sizes.

[0047] Material collection: After screening, fine aggregate particles of different sizes slide off the screen support frame 13. Since both the screen support frame 13 and the guide frame 24 are tilted to the lower left, the fine aggregate particles slide off the screen support frame 13 under the action of gravity onto the corresponding guide frame 24 below. The partition 25 on the guide frame 24 can be adjusted according to actual needs to achieve the classification, guiding and collection of materials of different sizes. Operators can place corresponding collection containers under the guide frame 24 to collect the screened fine aggregate particles, thus completing the entire screening and collection process.

[0048] Equipment Cleaning and Maintenance: After screening is completed, turn off the power to motor 7 and electric slide rail 20, and wait for the equipment to completely stop vibrating. Use tools to clean the residual cement mortar and fine aggregate particles from vibrating screen plate 14, plate 15, guide frame 24, and other parts of the equipment to avoid material residue affecting the next use of the equipment. Regularly check the wear of each component, such as the moving parts of motor 7, the contact parts between upper slide column 3 and lower slide seat 2, and the elasticity of spring 11. Replace severely worn parts in time. Check whether the bolts and nuts of each connection are loose. If they are loose, tighten them in time to ensure that the equipment is always in good working condition and extend the service life of the equipment.

[0049] In summary, the cement mortar vibrating screen of this utility model can achieve efficient vibration and precise grading of materials, optimize particle turning, facilitate material guiding and collection, and effectively improve the efficiency, accuracy and practicality of cement mortar fine aggregate screening.
