Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cement product manufacturing, in particular to a reciprocating screening device for raw materials used in cement product manufacturing. Background Art
[0002] Cement is commonly used in general civil engineering projects. General cement mainly refers to the six types of cement specified in GB175-2007, namely, Portland cement, ordinary Portland cement, slag Portland cement, pozzolanic Portland cement, fly ash Portland cement and composite Portland cement. When processing cement raw materials for subsequent processing, it is often necessary to screen the raw materials with a sieve plate to sort out large-diameter foreign matter in the raw materials.
[0003] The existing authorization announcement number CN218394612U is a reciprocating screening equipment for raw materials used in the manufacture of cement products, including a collecting box and a sieve plate, the collecting box is located below the sieve plate, a push plate is installed on the inner wall of the sieve plate, a support rod is installed on the inner wall of the push plate, a rack two is installed at one end of the support rod, a gear two is arranged outside the rack two, and the gear two is meshed with the rack two; a rack one is installed on the outer wall of one side of the sieve plate, a gear one is arranged outside the rack one, and the gear one is meshed with the rack one; a motor is arranged outside the sieve plate, the motor is used to drive the gear one and the gear two to rotate, and no manpower is required for screening, saving manpower, and at the same time, the push plate can move back and forth inside the sieve plate under the respective actions of the gear two and the spring two, so as to avoid the accumulation of raw materials at a certain place of the sieve plate, so that the screening effect is better, only one power element is needed, saving resources.
[0004] However, the device still has defects during specific use: first, the device uses spring one and spring two to re-engage and reset the half-gear. However, during use, the instability of the spring will cause the movement of the screen plate and the push plate to become unstable. This is because the meshing between the gear and the rack requires precision, and the elastic recovery of the spring takes time. Once a time error occurs between the two, after the half-gear rotates halfway, if the elasticity has not fully recovered its deformation, the half-gear will not be able to accurately mesh with the rack again, affecting the overall service life; secondly, the push plate in the device cannot be adjusted in height. When screening raw materials with different apertures, if the push plate does not change its height adaptively, it is easy to push the raw materials into the screen and block the screen, affecting the specific screening effect.

[0028] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.
[0029] See also Figure 1-Figure 7 A reciprocating screening device for raw materials used in cement product manufacturing comprises a bottom plate 1, bracket plates 2 are fixed on both sides of the top of the bottom plate 1, and guide rods 4 are fixed on the opposite sides of the two bracket plates 2, a guide plate 5 is slidably sleeved on the guide rod 4, and a first support plate 6 is fixed on the top of the guide plate 5, a second support plate 7 is fixed on the top of the first support plate 6, a fixing plate 8 is fixed on the side of the first support plate 6 and the second support plate 7 facing the center of the bottom plate 1, and a screening plate 9 is fixed between the two fixing plates 8; a collecting box 3 is arranged on the top of the bottom plate 1 below the screening plate 9;
[0030] A mounting plate 20 is also fixed to one side of the top of the bottom plate 1, and a motor 21 is installed on the mounting plate 20. The output end of the motor 21 is connected to a toothless gear 22. The opposite ends of one of the first support plate 6 and the second support plate 7 are both provided with teeth 23 meshing with the toothless gear 22. When the toothless gear 22 meshes with the teeth 23 on any of the support plates, the teeth 23 on the other support plate do not mesh with the toothless gear 22. Figure 6As shown, in this state, when the motor 21 drives the toothless gear 22 to rotate clockwise, the toothless gear 22 just begins to mesh with the teeth 23 on the first support plate 6 and has been disengaged from the teeth 23 on the second support plate 7. At this time, the clockwise rotation of the toothless gear 22 can enable the first support plate 6 to drive the fixed plate 8 and the screening plate 9 to move to the left, and the second support plate 7 will also move to the left. When the last tooth 23 on the first support plate 6 is disengaged from the toothless gear 22, the teeth 23 on the second support plate 7 just mesh with the toothless gear 22. At this time, the clockwise rotation of the toothless gear 22 will enable the second support plate 7 to drive the fixed plate 8 and the screening plate 9 to move to the right, and the first support plate 6 will also move to the right. In this way, when the motor 21 drives the toothless gear 22 to rotate, under the action of the teeth 23 on the first support plate 6 and the second support plate 7, the screening plate 9 can reciprocate left and right, thereby completing the screening of the cement product raw materials, and the screening stability effect is good and the service life is longer.
[0031] Furthermore, a plurality of scrapers 11 are arranged at equal intervals above the screening plate 9, and a connecting bar 12 is connected to the top of the scraper 11, and each connecting bar 12 is fixed by a support rod 15; a connecting plate 10 is arranged on the top of the fixed plate 8; a slide groove 14 is provided in the connecting plate 10, and a slider 13 is slidably connected inside the slide groove 14; both left and right ends of the connecting bar 12 penetrate the slider 13 and the connecting plate 10, and are fixedly connected to the slider 13;
[0032] Since the connecting strip 12 and the slider 13 are fixed, and the slider 13 can only slide in the slide groove 14, Figure 2 and Figure 4 It can be seen that the opening direction of the slide groove 14 is perpendicular to the movement direction of the screening plate 9, and since the movement of the screening plate 9 will cause the connecting plate 10 to move accordingly, the left and right movement of the connecting plate 10 will drive the slider 13 and the connecting bar 12 and the scraper 11 to move left and right synchronously. When the scraper 11 moves left and right, if an additional driving structure is used to drive the scraper 11 to move back and forth, the scraper 11 can be used to move back and forth during screening to evenly scrape the raw materials on the screening plate 9, thereby improving the screening effect.
[0033] Therefore, in order to facilitate the control of the scraper 11 to move forward and backward, a first magnet 17 is provided at both ends of one of the connecting strips 12, a transverse plate 16 is fixed on both bracket plates 2, and a second magnet 18 and a third magnet 19 are provided at one end of the transverse plate 16 facing the first magnet 17, and the first magnet 17 and the second magnet 18 are magnetically attracted to each other on opposite sides, and the first magnet 17 and the third magnet 19 are magnetically repelled from each other on opposite sides; since the transverse plate 16 is fixed on the bracket plate 2, it will not move by itself, and when the connecting strip 12 moves left and right, the first magnet 17 will also move left and right, thereby causing the first magnet 17 to separate from the second magnet 18. The first magnet 17 and the third magnet 19 cooperate with each other relatively, and because of the magnetic repulsion between the two, the connecting bar 12 will move away from the horizontal plate 16, and then the connecting bar 12 will return to its original position, so that the first magnet 17 cooperates with the second magnet 18 again, and then is sucked in the direction of the second magnet 18, and this cycle will make the screening plate 9 reciprocate left and right, and the connecting bar 12 will drive the scraper 11 to reciprocate back and forth, thereby completing the scraping of the raw materials, which is convenient for subsequent screening; in addition, if necessary, the magnet can also be replaced with an electromagnet to facilitate more accurate adjustment of the magnetic force and long-term use.
[0034] Furthermore, a card slot 24 is provided at the top of the fixed plate 8, a card plate 25 cooperating with the card slot 24 is provided at the bottom of the connecting plate 10, and a plurality of insertion holes 26 are provided on the card plate 25 at equal intervals; a positioning plate 27 is fixed to the top of the second support plate 7, and a plug rod 29 cooperating with the insertion hole 26 is provided through the top plate, and a spring 28 is connected between the outer wall of the plug rod 29 and the side of the positioning plate 27; by pulling out the plug rod 29 laterally, the spring 28 is compressed, and the plug rod 29 can be detached from the insertion hole 26, and then after adjusting the connecting plate 10 to a certain height, the plug rod 29 is inserted into another insertion hole 26, so that the height of the connecting plate 10 can be adjusted, and then the height of the scraper 11 can be adjusted, so as to meet the scraping requirements of raw materials with different particle sizes.
[0035] Furthermore, a movable groove 30 corresponding to the guide plate 5 is opened at the top of the base plate 1, and a ball 31 slidingly matched with the movable groove 30 is arranged at the bottom of the guide plate 5; the ball 31 slides inside the movable groove 30, so that the movement of the guide plate 5 is more stable, thereby improving the overall screening stability effect of the screening plate 9.
[0036] Furthermore, inclined plates 32 located below the screening plate 9 are fixed on opposite sides of the two fixed plates 8, and the inclined plates 32 cooperate with the collecting box 3; the inclined plates 32 can make it easier for the screened raw materials to enter the interior of the collecting box 3, thereby improving the use effect.
[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
