Description

Technical Field

[0001] This utility model relates to the field of adsorbent technology, specifically to a chemical adsorbent granulator. Background Technology

[0002] Adsorbents are a class of solid substances with special properties. Their core function is to adsorb target active ingredients onto their surface through physical or chemical interactions—especially by converting liquid trace compound additives into solid compounds, greatly facilitating uniform mixing in subsequent processes. From an essential perspective, high-quality adsorbents must meet several key indicators: First, they must possess a large specific surface area and suitable pore structure and surface chemical properties to provide sufficient adsorption sites; second, they must have strong selective adsorption capacity for the target adsorbate and not chemically react with the adsorbate or the surrounding medium under normal operating conditions, ensuring adsorption stability; third, they must balance ease of manufacturing and regeneration, while possessing excellent adsorption performance and mechanical strength—these characteristics collectively determine the application value of adsorbents in various fields such as water treatment, air purification, and chemical separation.

[0003] As a core branch of the adsorbent family, chemical adsorbents rely heavily on granulation machines in industrial production for their transformation from powder to granules. Chinese patent (publication / announcement number: CN116441151B) specifically discloses an adsorbent granulator and its supporting granulation method. Its main structure centers on the machine body: a hopper for raw material feeding is fixedly connected to the top of the body, ensuring stable material intake; a filter cartridge is fixedly installed on the outer side, forming an integrated system of "granulation-preliminary treatment." From a functional design perspective, the core innovation of this patent lies in the integration of the screening process: through power transmission from the output of a servo motor, the first and second filter plates rotate synchronously, allowing the adsorbent particles that have just been granulated to be screened immediately inside the equipment, directly separating defective and finished products. The significant advantage of this design lies in breaking the traditional separation model of "granulator + independent screening equipment," integrating the two processes into a single device. This reduces the investment cost of additional screening equipment and shortens the material transfer process from "granulation to screening," thus having a clear positive effect on improving the production efficiency of adsorbent particles. However, this patented technology still has obvious limitations in practical applications: although the integrated design eliminates the need for independent screening equipment, it does not fundamentally solve the core problem of screening effectiveness. Specifically, its screening relies on a single mode of "filter plate rotation," resulting in two key performance deficiencies: limited precision in size differentiation and insufficient screening thoroughness. Because the first and second filters screen simultaneously and side-by-side, the lack of a graded and progressive screening logic easily leads to some small defective products being directly discharged from the screening gap between the two filters. In particular, it is difficult to effectively separate "critical particles close to the qualified standard," which may ultimately lead to two problems: either the finished product contains a small number of unqualified particles, affecting product purity; or some qualified particles are misjudged as defective due to insufficient screening precision, resulting in raw material waste. Both of these situations require subsequent manual sorting, which increases labor costs to some extent and weakens the advantages of integrated design. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a chemical adsorbent granulator that can improve the screening effect, thus solving the problem that the chemical adsorbent granulator cannot improve the screening effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chemical adsorbent granulator, comprising: A pellet granulator includes a base, a frame is fixedly connected to the top left side of the base by bolts and nuts, a screening shell is fixedly connected to the top of the frame, a granulator box is fixedly connected to the top of the screening shell, a feed hopper is connected to the top of the granulator box, and the top of the screening shell is connected to the bottom of the granulator box. A screening mechanism, wherein the screening mechanism is disposed inside the screening machine housing; A screening machine includes a screening shell, a motor is fixedly connected to the left side of the screening shell, the output end of the motor passes through the screening shell and extends into the interior of the screening shell, and a drive shaft is fixedly connected thereto. A screening tank is fixedly connected to the right side of the drive shaft, a through hole is opened on the surface of the screening tank, a limit ring is fixedly connected to the right side of the screening tank, and a cover plate is movably connected to the right side of the screening shell through a hinge.

[0006] In a preferred embodiment of this invention, the screening mechanism includes a cylinder, which is fixedly connected to the four corners of the bottom of the screening machine housing. The output end of the cylinder passes through the screening machine housing and extends into the interior of the screening machine housing, where a lifting frame is fixedly connected. A screening screen is provided on the right side of the lifting frame, and connecting blocks are fixedly connected to both sides of the screening screen. The interior of the lifting frame is fixedly connected to the connecting blocks by bolts. A motor is fixedly connected to the left side of the inner wall of the lifting frame, and a vibrating cam is fixedly connected to the output end of the motor.

[0007] As a preferred embodiment of this utility model, upright plates are fixedly connected to both sides of the surface of the screening shell, and the bottom of the upright plates is fixedly connected to the right side of the top of the base.

[0008] As a preferred embodiment of this invention, a fixed bearing is fixedly connected to the surface of the transmission shaft, and the surface of the outer ring of the fixed bearing is fixedly connected to the inner wall of the screening shell.

[0009] As a preferred embodiment of this utility model, a handle is fixedly connected to the right side of the cover plate, and the surface of the handle is provided with anti-slip texture. A limiting plate is fixedly connected to the left side of the inner wall of the screening shell, and the right side of the limiting plate slides in contact with the left side of the screening tank.

[0010] As a preferred embodiment of this utility model, a connecting pipe is connected to the bottom right side of the screening machine casing, and a transmission pipe is connected to the bottom of the connecting pipe, with the bottom of the transmission pipe connected to the screening shell.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a granulator to process adsorbent raw materials through extrusion and pelletizing, transforming powdered raw materials into pre-formed chemical adsorbent granules, providing a uniform base material for subsequent screening. Then, the integrated screening mechanism performs a primary screening of the newly formed granules, separating granules or clumps significantly smaller than the acceptable size. Finally, a separate screening machine performs a secondary fine screening of the granules, causing qualified granules to fall to the bottom of the screening shell, while larger granules or clumps remain inside the screening tank. This secondary screening significantly improves the particle size uniformity and purity of the final product, reducing the cost of subsequent manual secondary sorting and minimizing the waste of raw materials due to qualified granules being mistakenly identified as substandard, effectively enhancing the screening effect and product quality stability of the entire production process.

[0012] 2. This utility model significantly improves the screening effect by setting up a screening mechanism. The cylinder can drive the lifting frame to move the screening screen up and down. The up and down movement of the screening screen causes the adsorbent particles to tumble, improving the screening efficiency. Then, the motor drives the vibrating cam to rotate, causing the screening screen to vibrate at high frequency, which effectively reduces the adhesion of particles to the surface of the screening screen, while enhancing the randomness of the movement trajectory of particles on the screening screen and improving the resolution accuracy of critical size particles.

[0013] 3. By setting up a vertical plate, this utility model provides a stable installation support for the screening machine, making the base of the screening machine and the granulator an integrated support structure. This avoids shaking during the operation of the screening machine, ensures the stability of the screening tank rotation, and prevents the particles from moving erratically in the screening tank due to equipment shaking, thus affecting the screening accuracy.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 5 As shown, the present invention provides a chemical adsorbent granulator, comprising: The pellet granulator 1 includes a base 101. A frame 102 is fixedly connected to the top left side of the base 101 by bolts and nuts. A screening machine shell 103 is fixedly connected to the top of the frame 102. A pelletizing machine box 104 is fixedly connected to the top of the screening machine shell 103. A feed hopper 105 is connected to the top of the pelletizing machine box 104. The top of the screening machine shell 103 is connected to the bottom of the pelletizing machine box 104. Screening mechanism 2 is located inside the screening machine housing 103; Screening machine 3 includes a screening shell 31. A motor 32 is fixedly connected to the left side of the screening shell 31. The output end of the motor 32 passes through the screening shell 31 and extends into the interior of the screening shell 31. A drive shaft 33 is fixedly connected to the inside of the screening shell 31. A screening tank 34 is fixedly connected to the right side of the drive shaft 33. A through hole 35 is opened on the surface of the screening tank 34. A limit ring 36 is fixedly connected to the right side of the screening tank 34. A cover plate 37 is movably connected to the right side of the screening shell 31 through a hinge.

[0018] refer to Figure 5The screening mechanism 2 includes a cylinder 21, which is fixedly connected to the four corners of the bottom of the screening machine housing 103. The output end of the cylinder 21 passes through the screening machine housing 103 and extends into the interior of the screening machine housing 103, where a lifting frame 22 is fixedly connected. A screening screen 23 is provided on the right side of the lifting frame 22. Connecting blocks 24 are fixedly connected to both sides of the screening screen 23. The interior of the lifting frame 22 is fixedly connected to the connecting blocks 24 by bolts. A motor 25 is fixedly connected to the left side of the inner wall of the lifting frame 22. A vibrating cam 26 is fixedly connected to the output end of the motor 25.

[0019] As a technical optimization of this utility model, by setting up a screening mechanism 2, the screening effect is significantly improved. The cylinder 21 can drive the lifting frame 22 to move the screening screen 23 up and down. The up and down movement of the screening screen 23 causes the adsorbent particles to tumble, improving the screening efficiency. Then, the motor 25 drives the vibrating cam 26 to rotate, causing the screening screen 23 to generate high-frequency vibration, which effectively reduces the adhesion of particles on the surface of the screening screen 23, while enhancing the randomness of the movement trajectory of particles on the screening screen 23, and improving the resolution accuracy of critical size particles.

[0020] refer to Figure 2 Both sides of the surface of the screening shell 31 are fixedly connected to the vertical plate 4, and the bottom of the vertical plate 4 is fixedly connected to the right side of the top of the base 101.

[0021] As a technical optimization of this utility model, by setting up the vertical plate 4, a stable installation support is provided for the screening machine 3, so that the screening machine 3 and the base 101 of the granulator 1 form an integrated support structure, which avoids the screening machine 3 from shaking during operation, ensures the stability of the screening tank 34 rotation and screening, and prevents the movement trajectory of particles in the screening tank 34 from being disordered due to equipment shaking, thus affecting the screening accuracy.

[0022] refer to Figure 3 A fixed bearing 5 is fixedly connected to the surface of the drive shaft 33, and the surface of the outer ring of the fixed bearing 5 is fixedly connected to the inner wall of the screening shell 31.

[0023] As a technical optimization of this utility model, by setting a fixed bearing 5, the transmission shaft 33 can be accurately positioned and stably supported, which can reduce the radial runout of the transmission shaft 33, ensure that the screening tank 34 always maintains stable coaxial rotation, and avoid the displacement of the through hole 35 on the surface of the screening tank 34 due to the shaking of the transmission shaft 33. This allows the particles to accurately pass through the through hole 35 to complete the screening, improves the uniformity and accuracy of screening, and solves the problem of the screening accuracy being affected by the instability of the transmission shaft 33 in traditional equipment.

[0024] refer to Figure 3A handle 6 is fixedly connected to the right side of the cover plate 37. The surface of the handle 6 is provided with anti-slip texture. A limiting plate 7 is fixedly connected to the left side of the inner wall of the screening shell 31. The right side of the limiting plate 7 is in sliding contact with the left side of the screening tank 34.

[0025] As a technical optimization of this utility model, by setting a handle 6, it is convenient for operators to quickly open and close the cover plate 37. After screening, the cover plate 37 can be opened in time to clean the unqualified particles remaining in the screening tank 34, so as to avoid the accumulation of residual particles affecting the screening effect of the next screening. The limiting plate 7 is slidably connected to the left side of the screening tank 34, which can play a limiting support role on the left side of the screening tank 34, further reducing the lateral displacement of the screening tank 34 when rotating, and ensuring that the screening tank 34 always rotates stably within the preset trajectory. In conjunction with the fixed bearing 5, the rotational stability of the screening tank 34 is further improved.

[0026] refer to Figure 1 A connecting pipe 8 is connected to the bottom right side of the screening machine casing 103, and a transmission pipe 9 is connected to the bottom of the connecting pipe 8. The bottom of the transmission pipe 9 is connected to the screening casing 31.

[0027] As a technical optimization of this utility model, the connecting pipe 8 and the transmission pipe 9 form a precise transmission channel for particles. The particles after preliminary screening by the screening mechanism 2 can enter the transmission pipe 9 through the connecting pipe 8, and then be precisely transported by the transmission pipe 9 to the screening shell 31 of the screening machine 3 for secondary screening. This avoids the particles from spilling or mixing with external impurities during the transfer process, and realizes a continuous process of "preliminary screening - precise transfer - secondary screening".

[0028] The working principle and usage process of this utility model are as follows: During use, the operator slowly feeds the chemical adsorbent raw material into the hopper 105 at the top of the granulator housing 104. The raw material enters the granulator housing 104 along the hopper 105. The granulator housing 104 processes the raw material using internally pre-set granulation components such as extrusion rollers and forming molds, based on the equipment's functional logic. Through extrusion, shaping, and other processes, the loose powder raw material is transformed into adsorbent particles. After granulation, the particles naturally fall into the screening mechanism 2 located inside the screening housing 103 under gravity. At this time, the screening mechanism 2 starts working, and the cylinders 21 at the four corners of the bottom of the screening housing 103 are connected... Upon receiving the control signal, the output end drives the lifting frame 22 to move up and down reciprocally. Simultaneously, the motor 25 on the left side of the inner wall of the lifting frame 22 starts. The output end of the motor 25 drives the vibrating cam 26 to rotate at high speed. During rotation, the vibrating cam 26 continuously impacts the protrusions of the screening screen 23, causing the screening screen 23 to vibrate at high frequency. The initial particles falling onto the screening screen 23 move continuously on its surface under the combined action of vibration and lifting. Particles that conform to the aperture size of the screening screen 23 fall through the mesh, while larger particles that do not conform to the aperture size remain on the screening screen 23, achieving initial screening. Particles that meet the specifications after initial screening are connected to the connecting pipe 8 at the bottom right side of the screening machine casing 103. The particles enter and are then precisely conveyed into the screening tank 34 inside the screening shell 31 by gravity and the guiding action of the transmission pipe 9 connected to the bottom of the connecting pipe 8. After the conveying is completed, the motor 32 of the screening machine 3 starts. The output end of the motor 32 passes through the screening shell 31 and drives the transmission shaft 33 to rotate repeatedly, which in turn drives the screening tank 34 fixedly connected on the right to rotate synchronously. At the same time, the limiting plate 7 on the left side of the inner wall of the screening shell 31 maintains sliding contact with the left side of the screening tank 34, which plays a limiting role in preventing the screening tank 34 from shifting laterally. During the repeated rotation of the screening tank 34, the particles inside continuously collide and roll with the inner wall of the screening tank 34, which is in line with the surface of the screening tank 34. Qualified particles with aperture 35 are thrown out through the through hole 35 into the screening shell 31 and are eventually collected at the bottom of the screening shell 31. Unqualified particles that do not conform to the aperture 35 remain inside the screening tank 34 and gradually move towards the right limit ring 36 as the screening tank 34 continues to rotate. After the equipment completes a batch of granulation and screening operations, the operator turns off the motor 32, motor 25 and cylinder 21. After the screening tank 34 has completely stopped rotating, the operator holds the handle 6 on the right side of the cover plate 37 and uses the anti-slip texture to increase the friction of the hand to open the cover plate 37 through the hinge. Then, the unqualified particles remaining inside the screening tank 34 are cleaned. After cleaning, the cover plate 37 is closed.

[0029] In summary, this chemical adsorbent granulator 1 processes the adsorbent raw material through extrusion and pelletizing, transforming the powdered raw material into pre-formed chemical adsorbent granules, providing a uniform base material for subsequent screening. Then, the integrated screening mechanism 2 performs a primary screening of the newly formed granules, separating granules or clumps significantly smaller than the acceptable size. Finally, a separately set screening machine 3 performs a secondary fine screening of the granules, causing the acceptable granules to fall to the bottom of the screening shell 31, while granules or clumps larger than the acceptable size remain inside the screening tank 34. This secondary screening significantly improves the particle size uniformity and purity of the final product, reducing the cost of subsequent manual secondary sorting and minimizing the waste of raw materials due to qualified granules being mistakenly identified as substandard, effectively enhancing the screening effect and product quality stability of the entire production process.
