Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of high-activity desulfurization agent processing, and particularly relates to a high-activity desulfurization agent processing and screening device. Background Art
[0002] Desulfurizers generally refer to agents used to remove free sulfur or sulfur compounds from fuels, raw materials, or other materials. In pollutant control and treatment, they primarily refer to agents used to remove sulfur oxides (including SO2 and SO3) from exhaust gases. This mixed solution desulfurizer exhibits surface activity and catalytic oxidation, promoting the direct reaction of SO2, accelerating the dissolution of CaCO3, promoting the rapid oxidation of CaSO3 to CaSO4, and enhancing CaSO4 precipitation. This reduces the liquid-to-gas ratio, lowers the calcium-to-sulfur ratio, and minimizes water evaporation. After production, the desulfurizer particles vary in size, requiring screening to separate them.
[0003] Chinese patent application number 2023217394081 discloses a particle size screening device for a fluorine-free, environmentally friendly desulfurizer, comprising a screening box and a crushing and drying mechanism. The screening box includes a feed hopper arranged on the top, and the crushing and drying mechanism includes a drying box located above the feed hopper. A bracket is provided between the drying box and the screening box. Two semicircular rotating baffles are rotatably provided inside the drying box. Two limiting members are provided between the rotating baffle and the drying box. A filter screen is provided in the drying box below the rotating baffle, and a crushing member is provided inside the drying box.
[0004] The patented solution combines a crushing component, a drying component, and a filter to crush and disperse the initial desulfurizer feed, while multiple screens simultaneously perform multi-stage screening of the desulfurizer. However, when using multiple screens, large particles of desulfurizer often accumulate on the upper screens during screening, requiring cleaning for optimal screening. This can disrupt continuous desulfurization. Utility Model Content
[0005] In order to solve the above problems, the utility model provides a high-activity desulfurizer processing screening device, including a screening frame, a feeding structure is provided on the top of the screening frame, and a first-level screening device and a second-level screening device are provided below the screening frame.

[0011] The advantages of the utility model are:
[0012] 1. This solution utilizes primary and secondary screening devices to effectively screen the desulfurizer at multiple levels, ensuring the appropriate particle size and improving screening efficiency and accuracy. The tilted first and second screening plates prevent accumulation on the screen, allowing for a continuous screening process and avoiding interruptions caused by screen buildup, thereby improving work efficiency.
[0013] 2. The use of vibration motors in this solution effectively improves screening efficiency.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. When an element is referred to as being "fixedly connected to" another element, it can be a common fixed connection method such as welding, bolt connection, or gluing connection. In short, for ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. Example 1
[0023] like Figure 1-2 As shown, a high-activity desulfurizer processing and screening device includes a screening frame 1, a feeding structure is provided on the top of the screening frame 1, and a primary screening device and a secondary screening device are provided below the screening frame 1. The primary screening device includes a first screening plate 2, a first screening mesh 3 is provided in the middle of the first screening plate 2, a connecting structure is provided around the top of the first screening plate 2, and the top of the connecting structure is connected to the top of the screening frame 1. The secondary screening device includes a second screening plate 4, a second screening mesh 5 is provided in the middle of the second screening plate 4, and a supporting device is provided around the bottom of the second screening plate 4, and the supporting device is connected to the bottom of the screening frame 1. The first screening plate 2 and the second screening plate 4 are inclined toward the lower right of the screening frame 1, a first conveyor belt 6 is provided at the lower right of the screening frame 1, and a second conveyor belt 7 is provided on the screening frame 1 below the second screening plate 4. The conveying directions of the two conveyor belts are opposite.
[0024] After falling from the feed structure, the desulfurizer is first screened by the first screening mesh 3 in the primary screening device. Because the first screening plate 2 is tilted, large particles of desulfurizer are intercepted by the first screening mesh 3 and then roll onto the first conveyor belt 6 under the action of gravity. The remaining desulfurizer passes through the first screening mesh 3 and then the second screening mesh 5. The larger particles of desulfurizer are intercepted by the second screening mesh 5 and also roll onto the first conveyor belt 6. The remaining small particles of desulfurizer pass through the second screening mesh 5 and enter the second conveyor belt 7, completing the screening process. Through the dual screening of the primary and secondary screening devices, the desulfurizer can be precisely separated according to particle size, ensuring the accuracy and reliability of the screening results. The use of tilted screening plates allows the desulfurizer to roll naturally during the screening process, reducing the need for manual intervention, operational difficulty, and labor intensity. At the same time, the tilted setting also promotes the uniform distribution of the desulfurizer on the screening mesh, improving the screening effect and screening speed.
[0025] Combine Figure 3-4 The feeding structure includes a feeding frame 8, a crushing part 9 is connected in the middle of the feeding frame 8, and a funnel part 10 is connected to the bottom of the crushing part 9. The first crushing roller 11 and the second crushing roller 12 are provided for rotation inside the crushing part 9. The first crushing roller 11 and the second crushing roller 12 are connected to corresponding drive motors. After the first crushing roller 11 and the second crushing roller 12 rotate, they can crush and disperse the desulfurizer fed initially to prevent the desulfurizer from becoming compacted and affecting screening. The design of the funnel part 10 connected to the bottom of the crushing part 9 allows the crushed and dispersed desulfurizer to enter the screening process smoothly and evenly. Since the desulfurizer has been crushed and dispersed before entering the screening process, the screening process is smoother, reducing the problems of screening blockage or reduced screening efficiency caused by uneven particle size or compaction. This not only improves the screening speed, but also makes the screening results more accurate and reliable.
[0026] A connecting rod 13 is connected to the bottom of the top of the screening frame 1, and a blower 14 is connected to the connecting rod 13. The blower 14 is directly opposite the top of the second screening plate 4. As the desulfurizer passes through the first screening mesh 3 and enters the second screening mesh 5, the blower 14 can generate a directional airflow that blows directly onto the desulfurizer, removing dust and impurities on the surface of the desulfurizer, thereby improving the purity of the desulfurizer and the screening quality. Because the blower 14 can blow away suspended impurities in the desulfurizer, these impurities will not clog the screening mesh, thus ensuring the smooth flow of the screening mesh and the stability of the screening speed. At the same time, a clean screening mesh can also improve screening accuracy, allowing desulfurizers of different particle sizes to be separated more accurately.
[0027] The connection structure includes a first vibration motor 15, the top of which is connected to the top of the screening frame 1. A vibration spring 16 is connected to the bottom of the first vibration motor 15, and the bottom of the vibration spring 16 is connected to the first screening plate 2. The support device includes a support frame 17, with support rods 18 connected around the bottom of the support frame 17. The top of the support frame 17 is connected to several second vibration motors 19, and the top of the second vibration motors 19 is connected to the bottom of the second screening plate 4. The first vibration motor 15 drives the first screening plate 2 to vibrate, while the second vibration motor 19 drives the second screening plate 4 to vibrate. The use of vibration motors can effectively improve screening efficiency. The first vibration motor 15 transmits vibration force to the first screening plate 2 via the vibration spring 16, causing it to vibrate, thereby promoting the flow and dispersion of the desulfurizer on the screening mesh. Similarly, the second vibration motor 19 drives the second screening plate 4 to vibrate, further enhancing the screening effect. This vibration helps break the adhesion between particles, making it easier for particles to pass through the screening mesh, thereby improving screening speed and accuracy. The introduction of a vibration motor also enhances the stability and reliability of the screening process. Vibration ensures that particles on the screen continuously tumble and bounce, preventing accumulation or clogging of the screen. This dynamic screening process not only improves screening efficiency but also ensures the stability and reliability of screening results.
[0028] The lower ends of the first screening plate 2 and the second screening plate 4 are both connected to a guide plate 20, and material guard plates 21 are provided on both sides of the first conveyor belt 6. First, the design of the guide plate 20 can effectively guide the desulfurizer particles after screening to flow to the designated collection area or conveyor belt. Since the two screening plates are arranged at an angle, the screened particles will roll along the screening plates under the action of gravity. By connecting the guide plate 20, it can be ensured that the particles fall into the first conveyor belt 6 more smoothly and accurately, avoiding the problem of particles scattering or deviating from the target area. The design of the material guard plate 21 can prevent the desulfurizer particles from scattering or overflowing during the transmission of the first conveyor belt 6. The material guard plates 21 are arranged along both sides of the conveyor belt, forming a protective barrier, which effectively limits the range of movement of the particles and ensures that the particles can be transported neatly and orderly on the conveyor belt. This not only reduces the loss and waste of particles, but also keeps the working environment clean and hygienic.
[0029] In summary, the design of connecting the lower ends of the first screening plate 2 and the second screening plate 4 to the guide plate 20, and providing material protection plates 21 on both sides of the first conveyor belt 6, has the advantages of guiding the flow of particles, preventing particles from scattering, improving screening efficiency, and enhancing equipment stability, further improving the performance and practicality of the high-activity desulfurizer processing and screening device.
