Description

Technical Field

[0001] This invention relates to the technical field of cement processing equipment, specifically to a cement processing screening device. Background Technology

[0002] Cement is a powdered hydraulic inorganic binder that forms a paste when mixed with water. It can harden in air or, even better, in water, and can firmly bind materials such as sand and stone together. For a long time, it has been widely used as an important binder in civil engineering, water conservancy, national defense and other projects.

[0003] However, during cement processing, in order to improve the quality of cement, it is necessary to screen the cement. When using existing cement screening equipment, the cement may clump or stick due to external factors during the screening process, which reduces the screening efficiency. At the same time, the equipment has difficulty in handling clumped cement, causing cement to remain inside the screening equipment and affecting the use of the screening equipment in the next cycle. Summary of the Invention

[0004] The purpose of this invention is to provide a cement processing screening device that effectively solves the problem that existing cement screening devices suffer from cement clumping or sticking due to external factors during the screening process, resulting in reduced screening efficiency. Furthermore, the device struggles to handle clumped cement, causing cement to remain inside the screening device and affecting its subsequent use.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a cement processing screening device, comprising a tank body, a support frame fixedly connected to the outside of the tank body, a feed pipe fixedly connected to a through hole provided at the top of the tank body, a discharge port provided at the bottom of the tank body, an anti-caking mechanism provided inside the tank body, and a screening mechanism provided inside the tank body;

[0006] The anti-caking mechanism includes a guide groove, a movable plate, a drive motor, an electric push rod, a squeezing assembly, an anti-caking assembly, a scraper, a drive rod, an anti-sticking rod, a dispersing rod, and a dividing rod. A guide groove is provided at the top of the tank. A movable plate is movably connected inside the guide groove. A drive motor is fixedly connected to the upper surface of the movable plate. The output end of the drive motor extends through the movable plate into the tank and is fixedly connected to an electric push rod. The output end of the electric push rod is fixedly connected to a squeezing assembly. An anti-caking assembly is movably connected to the lower surface of the squeezing assembly. A scraper is fixedly connected to the outer side of the squeezing assembly. A drive rod is fixedly connected to the lower surface of the squeezing assembly, and the bottom end of the drive rod passes through the anti-caking assembly and is fixedly connected to several anti-sticking rods. Several dispersing rods are fixedly connected to the outer side of the anti-sticking rods. Several dividing rods are provided between every two dispersing rods.

[0007] Through the above technical solution, the screening mechanism can quickly screen the cement, leaving the lumps or agglomerated cement clumps inside the screening mechanism. Then, the cement powder is stirred by the anti-caking mechanism to avoid excessive caking. Finally, the anti-caking component and the extrusion component work together to extrude and separate some of the lumps of cement, effectively preventing cement from clumping.

[0008] Preferably, the screening mechanism includes a screening box one, a double-layer screen, a fixed plate, a cam motor, a reset rod, a stabilizing spring, and a screening box two. The screening box one is disposed inside the tank body. A double-layer screen is fixedly connected to the inner side of the screening box one. A fixed plate is fixedly connected to the inside of the tank body. A cam motor is fixedly connected to the upper surface of the fixed plate, and the outer side of the output end of the cam motor contacts the outer side of the screening box one. One end of the reset rod is fixedly connected to the outer side of the screening box one. The other end of the reset rod is fixedly connected to the inner wall of the tank body. A stabilizing spring is disposed inside the reset rod. The screening box two is movably connected to the tank body through the reset rod.

[0009] Through the above technical solution, the screening mechanism of this application can achieve secondary screening through the double-layer screen set in the screening box, and the gap between the double-layer screen can intercept cement lumps. Then, the cement is separated by the use of the anti-caking component to avoid lumps.

[0010] Preferably, the extrusion assembly includes an extrusion disc, a mounting groove, a scraper, a limiting strip, and an extrusion spring. The output end of the electric push rod is fixedly connected to the extrusion disc. The extrusion disc is provided with a mounting groove. The extrusion disc is movably connected to the scraper through the mounting groove. Limiting strips are fixedly connected to the left and right sides of the scraper. A limiting strip is fixedly connected to the upper surface of the limiting strip.

[0011] Through the above technical solution, when there is cement clumping above the double-layer screen, the double-layer screen is set in a conical shape, causing the cement clumping to roll down to the vicinity of the extrusion assembly. Then, the electric push rod drives the extrusion assembly to move upward. Subsequently, the cement clumping moves to the top of the anti-caking assembly due to the shaking during screening. Then, the extrusion assembly extrudes the cement clumping through the extrusion disc and rotates using the drive motor. Then, the extrusion assembly is driven upward again by the electric push rod. Then, the scraper is exposed and indirectly drives the extrusion disc to rotate through the rotation of the drive motor. The extruded cement is scraped off by the arc-shaped scraper and continues to be screened.

[0012] Preferably, the anti-caking assembly includes a dispersion box, a feed inlet, a fixed pipe, a dispersion screen, a pressure plate, a magnet one, a magnet two, a guide strip, and a return spring. The dispersion box is fixedly connected to the inner side of the double-layer screen. The dispersion box has several feed inlets. The fixed pipe is fixedly connected to the inside of the dispersion box. Four dispersion screens are arranged on the outside of the fixed pipe. A pressure plate is arranged on the right side of the dispersion screen. A magnet one is fixedly connected to the upper surface of the pressure plate. Three magnet twos are fixedly connected to the outside of the drive rod. A guide strip is arranged between every two dispersion screens, and a return spring is arranged on the outside of the guide strip.

[0013] Through the above technical solution, the anti-caking component of this application uses the cooperation of magnet one and magnet two. When the extrusion component rotates with the electric push rod, the drive rod rotates, and then magnet two on the outside of the drive rod rotates and drives magnet one to move. Then, using the properties of magnets, magnet one drives the pressure plate to move, and through the guide rail set inside the dispersion box, the pressure plate pushes the cement clumps inside the dispersion box along the trajectory of the guide rail to push them against the dispersion screen, completing the separation of cement clumps. The cement then leaks out through the screen set at the bottom of the dispersion box. Then, magnet two continues to move, and due to the principle of like poles repelling each other, magnet one is given a pushing force, which, together with the return spring, causes magnet one to drive the pressure plate to quickly return to its original position, so that it will return to its original position just before the next magnet two arrives, making it convenient to use.

[0014] Preferably, the dispersion box is configured to correspond to a double-layer screen, with the top of the dispersion box aligned with the bottom of the upper screen of the double-layer screen, and the feed inlet of the dispersion box is located between the double-layer screens.

[0015] Through the above technical solution, the feed inlet of the dispersion box of this application is set between the double-layer screens to facilitate the entry of cement clumps between the double-layer screens into the dispersion box, which facilitates the subsequent separation and processing of the cement clumps.

[0016] Preferably, the scraper is used in conjunction with the double-layer screen, and the anti-sticking rod, dispersing rod and dividing rod are all located inside the screening box.

[0017] Preferably, the reset rod is configured as a two-section type, with the section farther away from screening box one and screening box two being configured as a fixed section, and the section closer to screening box one and screening box two being configured as a movable section.

[0018] By adopting the aforementioned technical solution, the beneficial effects of the present invention are:

[0019] 1. This cement processing screening device utilizes a screening mechanism and an anti-caking mechanism in combination. The screening mechanism processes the cement by screening during normal operation, while the anti-caking mechanism appropriately stirs the cement to reduce the probability of cement clumping. When cement lumps appear, the anti-caking mechanism compresses the lumps to achieve separation, thus preventing cement lumps from forming.

[0020] 2. This cement processing screening device, through the combined use of an anti-caking component and an extrusion component, allows the extrusion component to rotate and extrude cement with a large amount of caking in the screening mechanism, achieving a separation effect. Meanwhile, the anti-caking component further extrudes and screens some of the small caking cement lumps that have passed through the screening mechanism, making it convenient to use.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-5The present invention provides a technical solution: a cement processing screening device, including a tank body 1, a support frame 2 fixedly connected to the outside of the tank body 1, a feed pipe 3 fixedly connected to a through hole at the top of the tank body 1, a discharge port 4 at the bottom of the tank body 1, an anti-caking mechanism 5 inside the tank body 1, and a screening mechanism 6 inside the tank body 1.

[0029] The anti-caking mechanism 5 includes a guide groove 51, a movable plate 52, a drive motor 53, an electric push rod 54, an extrusion assembly 55, an anti-caking assembly 56, a scraper 57, a drive rod 58, an anti-sticking rod 59, a dispersing rod 510, and a dividing rod 511. A guide groove 51 is provided at the top of the tank body 1. A movable plate 52 is movably connected inside the guide groove 51. A drive motor 53 is fixedly connected to the upper surface of the movable plate 52. The output end of the drive motor 53 extends through the movable plate 52 into the tank body 1 and is fixedly connected to an electric push rod. The output end of the electric push rod 54 is fixedly connected to the extrusion assembly 55. The lower surface of the extrusion assembly 55 is movably connected to the anti-caking assembly 56. The outer side of the extrusion assembly 55 is fixedly connected to the scraper 57. The lower surface of the extrusion assembly 55 is fixedly connected to the drive rod 58, and the bottom end of the drive rod 58 passes through the anti-caking assembly 56 and is fixedly connected to several anti-sticking rods 59. The outer side of the anti-sticking rods 59 is fixedly connected to several dispersing rods 510. Several dividing rods 511 are provided between every two dispersing tubes.

[0030] Through the above technical solution, the screening mechanism 6 can quickly screen the cement, and then leave the cement lumps or agglomerated cement lumps in the screening mechanism 6. Then, the cement powder is stirred by the anti-caking mechanism 5 to avoid the occurrence of too many lumps. Then, the anti-caking component 56 and the extrusion component 55 work together to extrude and separate some of the cement lumps, effectively avoiding cement lumps.

[0031] Referring to Figures 2 and 5, the screening mechanism 6 includes a screening box 61, a double-layer screen 62, a fixing plate 63, a cam motor 64, a reset rod 65, a stabilizing spring 66, and a screening box 67. Screening box 61 is installed inside the tank 1. The double-layer screen 62 is fixedly connected to the inner side of screening box 61. The fixing plate 63 is fixedly connected to the inside of the tank 1. The cam motor 64 is fixedly connected to the upper surface of the fixing plate 63, and the outer side of the output end of the cam motor 64 contacts the outer side of screening box 61. One end of a reset rod 65 is fixedly connected to the outside of the first 61, and the other end of the reset rod 65 is fixedly connected to the inner wall of the tank 1. A stabilizing spring 66 is installed inside the reset rod 65. The tank 1 is movably connected to the second screening box 67 through the reset rod 65. The screening mechanism 6 can achieve secondary screening through the double-layer screen 62 set in the first screening box 61, and the gap between the double-layer screen 62 can intercept cement lumps. Then, the cement is separated by the use of the anti-caking component 56 to avoid caking.

[0032] Reference Figure 4 , 5 As shown, the extrusion assembly 55 includes an extrusion disc 551, a mounting groove 552, a scraper 553, a limiting strip 554, and an extrusion spring 555. The output end of the electric push rod 54 is fixedly connected to the extrusion disc 551. The extrusion disc 551 is provided with a mounting groove 552. The extrusion disc 551 is movably connected to the scraper 553 through the mounting groove 552. The left and right sides of the scraper 553 are fixedly connected to the limiting strip 554. The upper surface of the limiting strip 554 is fixedly connected to the limiting strip 554. When there is clump of cement above the double-layer screen 62, the double-layer screen 62 is set in a conical shape to... The clumped cement rolls down to the vicinity of the extrusion assembly 55. Then, the electric push rod 54 drives the extrusion assembly 55 to move upward. Subsequently, the clumped cement moves above the anti-clumping assembly 56 due to the shaking during screening. Then, the extrusion assembly 55 squeezes the clumped cement through the extrusion disc 551 and rotates using the drive motor 53. Then, the extrusion assembly 55 is driven upward again by the electric push rod 54. Then, the scraper 553 is exposed and indirectly drives the extrusion disc 551 to rotate through the rotation of the drive motor 53. The extruded and separated cement is scraped off by the arc-shaped scraper 553 and continues to be screened.

[0033] Reference Figure 2 , 3As shown in Figure 5, the anti-caking component 56 includes a dispersion box 561, a feed inlet 562, a fixed pipe 563, a dispersion screen 564, a pressure plate 565, a first magnet 566, a second magnet 567, a guide bar 568, and a return spring 569. The dispersion box 561 is fixedly connected to the inner side of the double-layer screen 62. The dispersion box 561 has several feed inlets 562. The fixed pipe 563 is fixedly connected inside the dispersion box 561. Four dispersion screens 564 are arranged on the outer side of the fixed pipe 563. A pressure plate 565 is arranged on the right side of each dispersion screen 564. A first magnet 566 is fixedly connected to the upper surface of the pressure plate 565. Three second magnets 567 are fixedly connected to the outer side of the drive rod 58. A guide bar 568 is arranged between every two dispersion screens 564, and a return spring 569 is arranged on the outer side of the guide bar 568. The anti-caking component 56 is designed to... The combined use of magnet 566 and magnet 567 allows the extrusion assembly 55 to rotate along with the electric push rod 54, causing the drive rod 58 to rotate. Subsequently, magnet 567 on the outside of the drive rod 58 rotates, moving magnet 566. Utilizing the properties of magnets, magnet 566 moves the pressure plate 565, which, along with the guide rail inside the dispersion box 561, pushes the cement clumps inside the dispersion box 561 towards the dispersion screen 564, separating the cement clumps and allowing them to pass through the screen at the bottom of the dispersion box 561. Magnet 567 then continues to move, and the principle of like poles repelling gives magnet 566 a thrust, which, combined with the return spring 569, causes magnet 566 to quickly return the pressure plate 565 to its original position, ensuring that the next magnet 567 is ready to return to its original position for convenient use.

[0034] Reference Figure 5 As shown, the dispersion box 561 is set corresponding to the double-layer screen 62. The top of the dispersion box 561 is consistent with the bottom of the upper screen of the double-layer screen 62, and the feed inlet 562 of the dispersion box 561 is set between the double-layer screen 62. The feed inlet 562 of the dispersion box 561 is set between the double-layer screen 62 to facilitate the entry of cement clumps between the double-layer screen 62 into the dispersion box 561, which is convenient for the subsequent separation and processing of cement clumps.

[0035] Reference Figure 2 , 5 As shown, the scraper 57 works in conjunction with the double-layer screen 62, and the anti-sticking rod 59, the dispersing rod 510 and the dividing rod 511 are all located inside the screening box 67.

[0036] Reference Figure 2 , 5 As shown, the reset rod 65 is configured as a two-section type, with the section farther away from screening box 1 61 and screening box 2 67 being a fixed section, and the section closer to screening box 1 61 and screening box 2 67 being a movable section.

[0037] When the cement processing screening device is working, the cement first enters the screening mechanism 6 through the feed pipe 3. Then, the screening box 61 is driven by the cam motor 64 to swing left and right to achieve the screening function. At the same time, the drive motor 53 is started, which drives the electric push rod 54 to rotate. Then, it further drives the extrusion component 55 to rotate. The rotation of the extrusion component 55 drives the scraper 57 to rotate to prevent the cement from clumping during the screening process. If there is cement clumping above the double-layer screen 62, the electric push rod 54 drives the extrusion component 55 to move upward. Then, the cement clumping moves to the top of the anti-caking component 56 due to the screening. Then, the electric push rod 54 pushes the extrusion component 55 downward and squeezes the cement clumping to separate it. Then, the electric push rod 54 moves upward again and is driven by the drive motor 53 to rotate. The extrusion component 55 pushes the separated cement blocks away through the scraper 553 and completes the screening through the double-layer screen 62.

[0038] When small cement lumps appear in the double-layer screen 62, the double-layer screen 62 pushes the small lumps to fall into the dispersion box 561 through the feed inlet 562. Then, the drive rod 58 rotates with the extrusion mechanism and drives the second magnet 567 to rotate. Then, the second magnet 567 drives the first magnet 566 to move. Furthermore, the first magnet 566 drives the pressure plate 565 to move and push the cement lumps inside the dispersion box 561 against the dispersion screen 564, completing the separation of the smaller cement lumps. The cement lumps fall through the screen at the bottom of the dispersion box 561. Then, the first magnet 566 leaves the second magnet 567 and the second magnet 567 provides thrust to work with the return spring 569 to reset the pressure plate 565 when the next second magnet 567 is about to arrive, which is convenient to use.

[0039] Subsequently, during screening in screening box 2 67, the cement is further screened by anti-sticking rod 59, dispersing rod 510 and dividing rod 511. The anti-sticking rod 59, dispersing rod 510 and dividing rod 511 rotate with drive rod 58, which effectively prevents the cement in screening box 2 67 from clumping. Finally, the screened cement is discharged through discharge port 4, thus completing the cement screening process.
