DETAILED DESCRIPTION
[0025] In order to make the purpose, technical scheme and advantages of the utility model clearer and more apparent, the utility model will be further described in detail below in combination with embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and not to limit the utility model.
[0026] Embodiment one
[0027] To solve the technical problems in the background art, a fly ash sintered brick raw material pretreatment device is given as follows:
[0028] In combination with Figures 1-7 , a fly ash sintered brick raw material pretreatment device is provided, which comprises a feeding bin 1 with an inclined top, a bearing frame 2 is attached to the inclined top of the feeding bin 1, a reciprocating mechanism 3 is arranged on the outer side of the upper part of the bearing frame 2, and a damping assembly 5 is arranged horizontally on the top surface of the lower part of the bearing frame 2; a material screen assembly 4 composed of an outer frame 41 and a screen 42 is slidably attached to the top of the bearing frame 2, the side portions of the outer frame 41 are respectively slidably connected to the limiting plates 6 of the inverted L-shaped structure which are vertically and symmetrically connected to the top surface of the bearing frame 2 on both sides; the bottom of the outer frame 41 is elastically connected to the damping assembly 5, and the top of the outer frame 41 is linearly drivingly connected to the reciprocating mechanism 3.
[0029] By adopting the above technical scheme, the pretreatment device integrates the screen cleaning action into the feeding process through the linkage structure of mechanical vibration and limiting guide, realizes integrated operation of screening and cleaning while maintaining compact layout (relying on original feeding bin modification), and has functionality, reliability and engineering adaptability.
[0030] The reciprocating mechanism 3 drives the material screen assembly 4 to move horizontally (in combination with the sliding clamping structure of the outer frame 41 and the limiting plate 6), the screen 42 automatically shakes off the excess material of the agglomerate under vibration, replaces manual scraper operation, reduces downtime cleaning time, and reduces the risk of worker falling or mechanical entanglement.
[0031] The damping assembly 5 is elastically connected to the bottom of the outer frame 41, which can cooperate with the fixed attachment design of the bearing frame 2 to absorb the impact and vibration energy of the raw material, avoid rigid collision between the screen 42 and the feeding bin 1, and reduce structural wear; and can also cooperate with the reciprocating mechanism 3 to drive the material screen assembly 4 to move horizontally.
[0032] The inverted L-shaped limiting plate 6 constrains the sliding track of the outer frame 41 to prevent the material screen assembly 4 from deviating or being stuck, ensures the continuity of reciprocating motion, and the inclined top design makes the excess material naturally slide to the designated area, avoiding secondary accumulation.
[0033] As Figure 2 , Figure 3 and Figure 6 ,Figure 7 As shown, preferably, the bottom of the bearing block is engaged with the mounting groove 11 opened on the inclined surface of the top opening of the feeding bin 1, and its top plate is integrally connected with a skirt 21 in the circumferential direction, and the outer edge of the skirt 21 is aligned with the edge of the inclined surface of the top opening of the feeding bin 1.
[0034] By adopting the above technical solution, the bottom of the bearing frame 2 is snapped into the mounting groove 11 on the inclined surface of the top opening of the feeding hopper 1 (instead of traditional bolt fixing), achieving rapid and accurate positioning and preventing the bearing frame 2 from shifting during vibration. The snap-fit structure combined with the inclined surface fitting design can disperse the lateral impact force generated by the screening operation, enhance the overall vibration resistance, and facilitate subsequent maintenance and disassembly.
[0035] The skirt 21 is aligned with the edge of the inclined surface of the top opening of the feeding bin 1 (forming a continuous covering ring edge), which can effectively prevent raw materials from overflowing from the joint between the bearing frame 2 and the feeding bin 1 during pouring, reducing material waste and equipment contamination. At the same time, the integrated skirt acts as a rigid reinforcing rib, which can disperse the local stress on the top plate of the bearing frame caused by the driving force of the reciprocating mechanism 3, preventing the frame from deforming and cracking, and extending its service life.
[0036] Example 2
[0037] Combination Figures 1-7 As shown, based on the above embodiments, this embodiment further provides the following:
[0038] In this embodiment, as Figures 1-4 As shown, the reciprocating mechanism 3 includes a support plate 31 that is inclinedly connected to the outer wall of the corresponding feeding bin 1; rectangular sliding frames 32 are vertically and symmetrically connected to both sides of the top surface of the support plate 31 along its centerline; two sliding frames 32 are inclinedly placed with sliding tongues 33 with arc-shaped upper ends; at least two sliders 331 are vertically and symmetrically connected to the sides of the sliding tongues 33, and the sliders 331 are laterally slidingly connected to the corresponding sliding frames 32; a round rod 35 is vertically connected to the lower end of the sliding tongue 33, and the round rod 35 passes through the gap and is vertically connected to the top surface of the bearing frame 2. The guide block 34 is located on the edge of the part, and the bottom end of the round rod 35 is hinged to the U-shaped bolt 411 vertically connected to the top of the outer frame 41; a limiting spring 351 is axially sleeved on the round rod 35, the lower end of the limiting spring 351 is connected to the guide block 34, and its upper end is connected to the lower end of the sliding tongue 33; a motor 36 is vertically arranged on the bottom surface of the upper end of the support plate 31, the power output end of the motor 36 passes through the outer side of the top surface of the support plate 31, and a cam 37 is axially vertically connected to it, which drives the sliding tongue 33 linearly and reciprocally under the drive of the motor 36.
[0039] By adopting the above technical scheme, the composite transmission mode of "cam + spring + inclined slide rail" is adopted to realize high-frequency low-amplitude vibration of the material screen assembly 4 in a limited space, which not only solves the pain point of manual screen cleaning, but also avoids the equipment resonance problem caused by direct installation of the traditional vibration motor, and has high efficiency and reliability.
[0040] The slide tongue 33 is in sliding cooperation with the inclined slide frame 32 through the slide block 331, and the rotational motion of the cam 37 is converted into the inclined linear reciprocating motion of the slide tongue 33 (the inclination angle of the slide frame 32 matches the inclined surface of the top opening of the feeding bin 1), and then the inclined linear reciprocating motion is converted into the horizontal vibration of the material screen assembly 4 through the round rod 35 and the U-shaped bolt 411; the multi-stage motion conversion structure (rotation→inclined linear→horizontal vibration) not only adapts to the inclined layout of the feeding bin, but also ensures that the screen mesh 42 generates effective horizontal shaking, thereby improving the disengagement efficiency of the excess material.
[0041] The limiting spring 351 is axially sleeved on the round rod 35, and the two ends are connected with the slide tongue 33 and the guide block 34, respectively. When the cam 37 drives the slide tongue 33: compression stage: the limiting spring 351 stores energy, and slows down the impact of the cam 37; rebound stage: the limiting spring 351 releases energy, and assists the slide tongue 33 to reset. This design avoids rigid impact, reduces the load fluctuation of the motor 36, and at the same time, through the gap cooperation of the guide block 34 to the round rod 35, the vibration trajectory is stable, and the material screen assembly 4 is prevented from yawing.
[0042] As shown in Figure 4 The bottom surface of the support plate 31 is respectively suspended and connected with the outer wall of the corresponding feeding bin 1 through the triangular structure of the reinforcing plate 311 matched therewith on both sides.
[0043] Through the above technical scheme, the mechanical optimization and space adaptation design of the triangular reinforcing plate 311 realize efficient transmission of dynamic load and vibration suppression in a limited installation space, which ensures the long-period stable operation of the reciprocating mechanism 3, and at the same time, the light weight and the convenience of modification are considered.
[0044] The triangular reinforcing plate 311 is symmetrically suspended and connected with the support plate 31 and the outer wall of the feeding bin 1 on both sides, forming a stable triangular support system. Its geometric characteristics (high bending stiffness of triangle) can uniformly transmit the vibration load (from the impact of the cam 37 and the vibration of the screen mesh 42) generated during the operation of the reciprocating mechanism 3 to the outer wall of the feeding bin 1, avoiding fatigue cracking of the root of the support plate 31 due to long-term alternating stress, and significantly improving the overall structural rigidity.
[0045] The suspension design of the reinforcing plate 311 makes the support plate 31 and the feeding bin 1 form a double fulcrum fixation, and in combination with the large-area contact surface of the triangular cross section, the transverse swing of the support plate caused by the high-speed rotation of the motor 36 and the cam 37 is effectively suppressed, the sliding trajectory of the slide tongue 33 and the slide frame 32 is ensured to be accurate, and the transmission deviation or jam caused by the vibration of the support plate is avoided.
[0046] As shown in Figures 5-7 The material blocking plate 412 is vertically and symmetrically connected to the top surface of the outer frame 41 on both sides and close to the edge of the screen 42.
[0047] By adopting the above technical solution, the double-sided material blocking plate 412 has the functions of blocking and counterweight, which realizes dynamic constraint and mechanical balance of the screening process in limited space, improves screening accuracy, enhances equipment operation stability, and further reduces the need for manual intervention.
[0048] The material blocking plate 412 is vertically and symmetrically connected to the top surface of the outer frame 41 on both sides and close to the edge of the screen 42.
[0049] The material blocking plate 412 is rigidly connected to the outer frame 41, and the symmetric distribution of the structure makes it form a double-sided counterweight balance during the vibration of the screen 42, which offsets the eccentric moment caused by the unilateral driving of the reciprocating mechanism 3, reduces the abnormal wear of the sliding joint between the outer frame 41 and the limiting plate 6, and ensures the linearity and continuity of the vibration trajectory.
[0050] Embodiment Three
[0051] In combination with Figure 6 and Figure 7 Based on the above embodiments, the present embodiment further provides the following contents:
[0052] In the present embodiment, as shown in Figure 6 and Figure 7 The damping assembly 5 includes a U-shaped groove 51 vertically connected to the lower top surface of the bearing frame 2, a pad 52 vertically and slidingly arranged in the U-shaped groove 51, and a plurality of damping springs 53 vertically and symmetrically connected between the pad 52 and the inner vertical surface of the U-shaped groove 51 at equal intervals.
[0053] By adopting the above technical solution, the composite damping structure of "U-shaped groove + sliding pad + multiple spring array" realizes the step-by-step dissipation of high-frequency vibration energy in limited space, which not only guarantees the screening efficiency, but also avoids the equipment resonance problem caused by traditional rigid connection, and has dynamic stability and maintenance friendliness.
[0054] The U-shaped groove 51 and the sliding clamping of the backing plate 52 (the outer frame 41 extends into the U-shaped groove 51) are combined with the equally spaced shock-absorbing springs 53 to form a multi-stage vertical buffer: first-stage shock absorption: when the screen 42 vibrates, the outer frame 41 drives the backing plate 52 to slide in the U-shaped groove 51 through the fastening bolt 521, and the high-frequency vibration energy is absorbed by the compressed shock-absorbing springs 53; second-stage shock absorption: the U-shaped groove 51 is rigidly connected with the bearing frame 2, and the low-frequency impact force is further dispersed through the deformation of the groove body itself, so as to avoid the direct transmission of vibration to the feeding bin 1. The design effectively reduces the impact of the screening operation on the overall structure and prolongs the service life of the equipment.
[0055] The equally spaced vertical layout of the shock-absorbing springs 53 can be adapted to different raw material processing requirements by adjusting the spring stiffness or quantity (such as replacing springs of different specifications).
[0056] The cover plate 54 and the cover structure of the U-shaped groove 51 not only prevent dust from entering the groove to corrode the springs, but also allow direct maintenance or replacement of the springs / backing plate 52 by disassembling the cover plate, without the need to disassemble the entire material screen assembly 4, thereby significantly reducing maintenance costs.
[0057] The sliding clamping of the backing plate 52 and the U-shaped groove 51 (the gap is controllable) restricts the vibration amplitude of the outer frame 41, avoiding the derailment of the material screen assembly 4 due to excessive driving force of the reciprocating mechanism 3. At the same time, the fastening bolt 521 leaves a small amount of elastic allowance when fixing the outer frame 41 and the backing plate 52, allowing the screen 42 to self-adaptively fine-tune in the horizontal plane, ensuring that the vibration trajectory is consistent with the guidance of the limiting plate 6.
[0058] As shown in Figure 7 The inner side of the cover plate 54 is integrally connected with a transition ridge 541 of arc-shaped structure, and the bottom surface of the transition ridge 541 is gap-tightly connected with the top surface of the outer frame 41.
[0059] By adopting the above technical scheme, the arc-shaped structure of the transition ridge 541 is gap-tightly connected with the top surface of the outer frame 41 (about 1-3 mm gap), forming a flexible contact interface: vibration adaptability: when the outer frame 41 vibrates horizontally, the arc surface follows and fits, avoiding hard friction, and at the same time, blocking the dust raised during the screening process from entering the inside of the U-shaped groove 51 from the gap between the cover plate 54 and the outer frame, protecting the shock-absorbing springs 53 from pollution and corrosion; guiding the material: the arc surface can guide the large block of material rolled on the screen 42 to fall to the ground outside the feeding bin 1, preventing the material from being trapped and blocked at the cover plate 54.
[0060] The transition ridge 541 is integrally connected with the cover plate 54 (non-welding or bolt fixation), and the arc-shaped protrusion extending along the long side of the cover plate 54 forms a longitudinal reinforcing rib, significantly improving the bending stiffness of the cover plate 54, avoiding the collapse and deformation of the middle part of the cover plate due to the repeated compression and rebound of the shock-absorbing springs 53 in the U-shaped groove 51. At the same time, the gap-tight connection between it and the outer frame 41 produces a slight damping effect, which can absorb the high-frequency vibration energy of the screen 42 and reduce the overall noise.
[0061] The working principle and use process of the utility model are as follows:
[0062] In use, the forklift pours raw materials such as fly ash and clay into the top opening of the feeding bin 1 according to the proportion, and the raw materials first fall onto the surface of the screen 42 of the material screening assembly 4. Since the inclined surface of the top opening of the feeding bin 1 and the skirt edge part 21 of the bearing frame 2 are seamlessly aligned with the bin body, the raw materials are guided and concentrated to the central area of the screen 42. The material blocking plates 412 on both sides block the side overflow of the materials, and ensure that the screening range is controllable.
[0063] The motor 36 of the reciprocating mechanism 3 is started, the cam 37 is driven to rotate, the slide tongue 33 is pushed to make linear reciprocating movement along the inclined slide frame 32. The slide tongue 33 drives the outer frame 41 and the screen 42 to vibrate horizontally (the amplitude is buffered and adjusted by the limiting spring 351) through the round rod 35 and the U-shaped bolt 411. The vibration of the screen 42 makes the qualified fine materials fall through the screen into the lower belt, and the materials that are wet and blocked are retained on the screen surface due to the large particle size, and are moved downward along the inclined screen surface with the vibration, and finally automatically slide from the bottom edge of the screen 42 to the collection area outside the feeding bin, without manual scraping.
[0064] The above only describes the preferred embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
