Description

Technical Field

[0001] This application relates to the field of refractory castable processing technology, specifically to a screening and receiving device for refractory castable aggregates. Background Technology

[0002] Screening of aggregates for refractory castables is a crucial step in the production of high-quality refractory materials. Precise screening not only ensures that the particle size distribution of the final product meets specific requirements, but also removes impurities and large, uncrushed particles, thereby improving product performance and service life.

[0003] Traditional screening equipment often uses a single-stage screening structure, which results in 20-30% of qualified fine particles being screened out along with coarse materials. Secondly, the particle size control is not precise, making it difficult to meet the screening requirements of 3-8mm. Moreover, it often uses a vibrating motor for screening, but the vibrating motor is noisy and also has a huge impact on the springs, causing the damping system to wear out quickly. Summary of the Invention

[0004] The technical problem to be solved by this application is to overcome the existing defects and provide a screening and receiving device for refractory castable aggregates, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a screening and receiving device for refractory castable aggregate, comprising a main support base, a worktable of the main support base connected to a pad seat, a material screening group connected to the pad seat, the material screening group comprising multi-stage screening components and screening drive components, the multi-stage screening components comprising a screening frame, an intermediate connecting seat, a primary screening plate and a secondary screening plate, the secondary screening plate being installed between the screening frames, and an intermediate connecting seat being provided between the secondary screening plate and the primary screening plate;

[0006] The screening drive unit consists of a support connection group, a drive group, and a transmission assembly. The support connection group is located below the outer casing and is connected to the transmission assembly. The transmission assembly includes a rotating guide shaft, a drive wheel, a displacement adjustment shaft, a displacement slide plate, and a guide slide block. The displacement slide plate is slidably connected inside the guide slide block. A strip groove is provided in the middle of the displacement slide plate. Drive wheels are sleeved on both sides of the rotating guide shaft. A displacement adjustment shaft is provided on the drive wheel and is sleeved in the strip groove.

[0007] As a preferred technical solution of this application, the pad seat is symmetrically provided with elastic seats. The elastic seats include elastic brackets, connecting cross braces and right angle plates. The elastic brackets are connected to the connecting cross braces by fasteners. A right angle plate is provided on one side of the connecting cross brace and the right angle plate is connected to one side of the outer shell.

[0008] As a preferred technical solution of this application, the support connection group includes a bearing seat and a connecting shaft. The bearing seat is disposed on both sides of the lower surface of the outer cover, and the connecting shaft is sleeved between the two. The connecting shaft is sleeved with the displacement slide plate in the transmission assembly.

[0009] As a preferred technical solution of this application, the drive assembly includes a motor mounting bracket, a drive motor, a drive wheel, and a driven wheel. The drive motor is provided on one side of the motor mounting bracket, and the output end of the drive motor is connected to the drive wheel. The drive wheel and the driven wheel provided on the rotating guide shaft in the transmission assembly are connected by a transmission belt.

[0010] As a preferred technical solution of this application, the main support is further provided with a receiving hopper, which is configured to correspond to the discharge port of the multi-stage screening component.

[0011] As a preferred technical solution of this application, an auxiliary support is also provided on the outer side of the main support, the upper surface of the auxiliary support is provided with a horizontal support bar, and the end of the auxiliary support is provided with a baffle.

[0012] As a preferred technical solution of this application, the outer sides of the screening frame, the intermediate connecting seat, the primary screening plate and the secondary screening plate are covered with a steel plate outer shell, and a feed inlet is provided at one end of the outer shell, which is located above the primary screening plate.

[0013] Compared with existing technologies, this application utilizes a primary and secondary screening plate to achieve continuous and precise grading and screening. Compared to traditional single-stage screening structures, it can more effectively separate materials of different particle sizes, reduce the loss of qualified fine particles, ensure that the particle size of the product meets requirements, and the precise screening mechanism avoids the problem of qualified fine particles being mistakenly screened out in traditional equipment, thereby improving material utilization and reducing unnecessary waste. Furthermore, unlike traditional vibratory motor drives, this application employs a transmission assembly consisting of a rotating guide shaft and drive wheel to convert rotational motion into linear reciprocating motion for vibratory screening. This reduces operating noise levels and minimizes impact on the spring damping system, extending its service life. The improved working environment helps protect the hearing health of operators and provides a quieter and more comfortable working space. Attached Figure Description

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0021] Please see Figure 1-5 This application provides a technical solution: a screening and receiving device for refractory castable aggregates, including a main support 6, wherein a pad seat 9 is connected to the worktable of the main support 6.

[0022] The main support 6 is the supporting frame of the entire device. It is made of high-strength steel and welded to ensure that the equipment remains stable during the vibrating screening process. The worktable is used to install the pad seat 9 and bear the weight of the entire screening system.

[0023] The pad seat 9 connects the main support seat 6 and the material screening group, serving as a transitional support. It is usually fixed with bolts for easy disassembly and maintenance. Its surface is flat, ensuring that the screening frame 10 remains horizontal during installation and avoiding uneven screening due to tilting.

[0024] The pad seat 9 is connected to a material screening group, which includes a multi-stage screening component. The multi-stage screening component includes a screening frame 10, an intermediate connecting seat 23, a primary screening plate 24, and a secondary screening plate 25. The secondary screening plate 25 is installed between the screening frames 10, and an intermediate connecting seat 23 is provided between the secondary screening plate 25 and the primary screening plate 24.

[0025] The screening frame 10 is welded from channel steel or square tube, forming the main support of the screening structure. Its internal space is used to install the primary screening plate 24 and the secondary screening plate 25 to ensure that the screening plate does not deform during vibration.

[0026] The intermediate connecting seat 23 is located between the primary screening plate 24 and the secondary screening plate 25, serving to connect and fix them. It can also adjust the distance between the two screening plates, adopting an adjustable design to facilitate the adjustment of the screening gap according to the aggregate particle size.

[0027] The primary screening plate 24 typically uses a screen with a larger aperture (e.g., 10-20 mm) to initially remove coarse aggregate particles, such as large impurities or uncrushed raw materials. The secondary screening plate 25 has a smaller screen aperture (e.g., 3-8 mm) for fine screening, ensuring that the final aggregate meets the particle size requirements of refractory castables. It forms a continuous screening process with the primary screening plate 24, improving production efficiency.

[0028] The sieve plate material needs to be wear-resistant and impact-resistant, and high manganese steel or composite metal mesh are often used.

[0029] The material screening group also includes a screening drive component, which consists of a support connection group, a drive group and a transmission component. The support connection group is located below the outer casing 2 and is connected to the transmission component.

[0030] The support connection group is mainly responsible for providing physical support and ensuring the stability and reliability of the entire screening drive. It is located below the outer casing 2 and connected to the transmission assembly. The drive group is the power source of the screening drive and is responsible for providing the necessary kinetic energy for the entire screening process. The transmission assembly is responsible for converting the kinetic energy provided by the drive group into a vibration mode suitable for the screening process, so as to realize the grading and screening of materials. The support connection group, drive group and transmission assembly each perform different functions, but they cooperate with each other to ensure the efficiency and stability of the screening process.

[0031] The transmission assembly includes a rotary guide shaft 22, a drive wheel 15, a displacement adjustment shaft 21, a displacement slide plate 14, and a guide slide block 16. The displacement slide plate 14 is slidably connected inside the guide slide block 16. A strip groove is provided in the middle of the displacement slide plate 14. The drive wheel 15 is sleeved on both sides of the rotary guide shaft 22. The displacement adjustment shaft 21 is provided on the drive wheel 15 and is sleeved in the strip groove.

[0032] The rotating guide shaft 22 has drive wheels 15 installed at both ends to convert the rotational motion of the driven wheel 20 into the rotational motion of the drive wheels 15. The drive wheels 15 generate reciprocating driving force through rotation. The wheel rim is provided with a displacement adjustment shaft 21, which adjusts the amplitude by changing its position in the strip groove. The displacement slide plate 14 has a strip groove in the middle, which cooperates with the displacement adjustment shaft 21 to convert the rotational motion into linear reciprocating motion. The guide slide 16 provides a precision guide rail structure for the displacement slide plate 14 to ensure the linear motion accuracy of the displacement slide plate 14.

[0033] Furthermore, the pad seat 9 is symmetrically provided with elastic seats, each elastic seat including an elastic bracket 11, a connecting cross brace 8 and a right angle plate 7. The elastic brackets 11 are connected to the connecting cross brace 8 by fasteners. A right angle plate 7 is provided on one side of the connecting cross brace 8 and is connected to one side of the outer cover 2.

[0034] The elastic support 11 is made of high-strength spring steel and has three-dimensional elastic deformation capability. It absorbs the mechanical vibration generated during the screening process and reduces the impact force transmitted to the frame. The two ends of the connecting cross brace 8 are rigidly connected to the elastic support 11 by high-strength bolts to maintain synchronous movement on both sides and enhance the overall structural stability. The right angle plate 7 has an elongated hole, which allows the outer cover 2 to have a displacement of ±3mm, realizing the flexible connection between the vibrating component and the fixed component.

[0035] Furthermore, the support connection assembly includes a bearing seat 12 and a connecting shaft 13. The bearing seat 12 is disposed on both sides of the lower surface of the outer cover 2, and the connecting shaft 13 is sleeved between the two. The connecting shaft 13 is sleeved with the displacement slide plate 14 in the transmission assembly.

[0036] The bearing seats 12 are located on both sides of the lower surface of the outer casing 2, providing a stable foundation support for the entire screening device. The connecting shaft 13 passes through the two bearing seats 12, playing a connecting and stabilizing role, ensuring that the displacement slide plate 14 in the transmission assembly can receive the necessary support.

[0037] Furthermore, the drive assembly includes a motor mounting bracket 19, a drive motor 17, a drive wheel 18, and a driven wheel 20. The drive motor 17 is provided on one side of the motor mounting bracket 19, and the output end of the drive motor 17 is connected to the drive wheel 18. The drive wheel 18 and the driven wheel 20, which is provided on the rotating guide shaft 22 in the transmission assembly, are connected by a transmission belt.

[0038] The motor mounting bracket 19 is used to fix the drive motor 17. This ensures the drive motor 17 remains stable during operation, preventing positional displacement due to vibration or external forces, thus guaranteeing the normal operation of the entire screening device. The drive motor 17 is the core of the entire screening drive system. Its output end is connected to the drive wheel 18, which generates kinetic energy through rotation. This energy is then transferred to the screening device via a transmission assembly, providing the necessary power support for the material screening process. The drive wheel 18 is directly connected to the output shaft of the drive motor 17; when the drive motor 17 operates, the drive wheel 18 begins to rotate. The driven wheel 20 is mounted on the rotating guide shaft 22, and the two are connected by a transmission belt. This effectively transmits the kinetic energy generated by the drive motor 17 to the rotating guide shaft 22, thereby driving the movement of the entire screening system.

[0039] Furthermore, the main support 6 is also provided with a receiving hopper 3, which is correspondingly set with the discharge port of the multi-stage screening component.

[0040] The receiving hopper 3 is mounted on the main support 6 and corresponds to the discharge port of the multi-stage screening component. It collects the screened material. Precise alignment with the discharge port of the screening component ensures that the screened material falls accurately into the receiving hopper 3, avoiding waste or contamination.

[0041] Furthermore, an auxiliary support is provided on the outer side of the main support 6, with a horizontal support bar 5 on the upper surface of the auxiliary support and a baffle 4 at the end of the auxiliary support.

[0042] The auxiliary support is set on the outside of the main support 6 to further enhance the stability and robustness of the overall structure.

[0043] The cross brace 5 is located on the upper surface of the auxiliary support frame. It is used to strengthen and increase the rigidity and stability of the overall frame, and to provide support for the receiving hopper 3, thereby improving the ease of use.

[0044] Baffle 4 is located at the end of the auxiliary support frame, serving both protective and guiding functions. It helps guide materials smoothly into the receiving hopper 3 or other designated areas, improving the efficiency and accuracy of material collection.

[0045] Once collection is complete, the user pulls the receiving hopper 3 out of the auxiliary support frame and unloads the material from the receiving hopper 3. After unloading, the receiving hopper 3 is reset for the next collection.

[0046] Furthermore, the outer sides of the screening frame 10, the intermediate connecting seat 23, the primary screening plate 24 and the secondary screening plate 25 are covered with a steel plate outer shell 2, and one end of the outer shell 2 is provided with a feed inlet 1, which is located above the primary screening plate 24.

[0047] The outer casing 2 is made of steel plate and covers the outside of the screening frame 10 and the screening plate, serving a protective and sealing function. It prevents dust from flying during the screening process, reduces environmental pollution, and also prevents foreign objects from entering the equipment, affecting the screening effect or damaging the equipment.

[0048] More specifically, the upper side of the outer casing 2 has a hinged structure, which can be opened to inspect and maintain the internal material screening group, improving the convenience of later use.

[0049] The feed inlet 1 is located at one end of the outer casing 2 and above the primary screening plate 24, and is used to uniformly feed the refractory castable aggregate to be screened into the screening device. This ensures that the material can smoothly enter the primary screening plate 24 for preliminary screening.

[0050] In use: The refractory castable aggregate to be screened is evenly added into the device through the feed port 1 located at one end of the outer casing 2. The drive motor 17 is started, and the drive wheel 18 rotates accordingly, driving the driven wheel 20 and the rotating guide shaft 22 to rotate via the transmission belt. As the rotating guide shaft 22 rotates, the drive wheel 15 moves. The rotation is converted into linear reciprocating motion through the displacement adjustment shaft 21 and the strip groove, causing the displacement slide plate 14 to slide in the guide slide 16, thereby causing the entire material screening group to move up and down and generate the necessary vibration. Under the action of vibration, the primary screening plate 24 first screens the material. Coarse screening removes large impurities or unbroken raw materials. After primary screening, the material falls into secondary screening plate 25 for finer screening to ensure that the final aggregate meets the particle size requirements of refractory castable. The dust generated during screening is effectively controlled by the outer casing 2, reducing environmental pollution and protecting the safety of the working environment. After two stages of screening, the material falls into the receiving hopper 3 from the corresponding discharge port. When the screening operation is completed, the drive motor 17 is stopped, the receiving hopper 3 is opened, and the screened material is discharged. After the discharge is completed, the receiving hopper 3 is reset for the next use.
