Description

Technical Field

[0001] This utility model relates to the technical field of particle vibration screening equipment in the chemical production of nylon chips, and specifically to a particle dispersion device for particle screening. Background Technology

[0002] In the chemical production of nylon chips, particle vibrating screens are commonly used. After the material strips are granulated by a pelletizer, they are dehydrated in a pre-dryer and then enter the upper screen plate of the vibrating screen through a pipeline into the inlet box. The particles are screened on the upper screen plate; particles that meet the size requirements fall through the upper screen holes onto the lower screen plate and enter the buffer hopper; irregularly shaped particles that do not meet the size requirements cannot enter the screen holes and enter the irregular particle collection hopper at the end of the upper screen plate. Previously granulated particles, after passing through the pre-dryer, enter the vibrating screen inlet box through a pipeline. Because the pipeline from the pre-dryer to the inlet box is circular, the particles concentrate at the bottom of the pipeline when falling onto the screen plate. At high pelletizing speeds, this can cause material buildup at the inlet box, leading to interruptions in the pelletizing process. Furthermore, not all the qualified particles that are concentrated together fall through the screen holes onto the lower screen plate; some qualified particles enter the irregular particle pipeline along with the irregular particles, increasing the total amount of irregular particles and increasing costs.

[0003] The current problem to be solved is how to design a particle dispersion device for particle screening that has a reasonable and ingenious structure, can stably disperse particles during the slicing and screening process, avoid particle accumulation at the particle inlet tube box when the granulation speed is high, ensure the continuity of the granulation process, effectively reduce costs, increase the qualified product quantity, and improve enterprise efficiency. Utility Model Content

This device features a reasonable structure and ingenious design, stably dispersing particles during the slicing and screening process. It prevents particle accumulation at the particle inlet box during high-speed pelleting, ensuring the continuity of the pelleting process, effectively reducing costs, increasing the quantity of qualified products, and improving enterprise efficiency.

[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0019] As shown in the figure, a particle dispersion device for particle screening includes a first vibrating motor 1, a vibrating screen support frame 2, an upper screen plate 3, screen holes 4, a shaped particle collection hopper 5, a shaped particle outlet pipe 6, a particle inlet pipe 7, a particle inlet box 8, a particle dispersion plate 9, a second vibrating motor 10, a lower screen plate 11, an ultrafine particle outlet 12, a qualified material outlet 13, and a flexible connection 14. The particle inlet box 8 is located above the front end of the vibrating screen support frame 2, and the upper screen plate 3 and the lower screen plate 11 are arranged inside the vibrating screen support frame 2. The shaped particle collection hopper 5 is located at the rear end of the vibrating screen support frame 2, and the shaped particle outlet... The inlet pipe 6 is located at the lower end of the irregular particle collection hopper 5, and the upper end of the irregular particle collection hopper 5 is connected to the tail end of the upper sieve plate 3; the qualified material outlet 13 is located at the tail end of the lower sieve plate 11 to receive qualified particles; the ultrafine particle outlet 12 is located below the lower sieve plate 11 to receive ultrafine particles; the particle dispersion plate 9 is located on the upper sieve plate 3, and the particle dispersion plate 9 includes two symmetrical wing plates on the left and right, the connection between the two wing plates forms an obtuse angle, the height of the wing plates gradually decreases from the center to both sides, forming an arc-shaped edge, and the arc-shaped edge is used to gradually disperse the particles accumulated below the particle inlet box 8.

[0020] The above is the basic implementation of this utility model. Further improvements, refinements and limitations can be made on the basis of the above: for example, the first vibration motor 1 and the second vibration motor 10 are respectively arranged on the left and right sides of the vibrating screen support frame 2.

[0021] The above is the basic implementation of this utility model. Further improvements, refinements and limitations can be made on the basis of the above: as described, the particle inlet pipe 7 is set above the particle inlet box 8, and the particle inlet pipe 7 and the top of the particle inlet box 8 are connected by a flexible connection 14.

[0022] As shown in the figure, the working process of this utility model is as follows: Particles fall from the particle inlet pipe 7 through the particle inlet box 8 onto the upper sieve plate 3. The particles falling onto the upper sieve plate 3 are concentrated directly below the particle inlet pipe 7. The vibrating screen support frame 2 vibrates up, down, forward, and backward under the action of the first vibrating motor 1 and the second vibrating motor 10. The upper sieve plate 3 and the lower sieve plate 11 vibrate together with the vibrating screen support frame 2. The particles concentrated directly below the particle inlet pipe 7 move towards the shaped particle outlet pipe 6 with the vibration of the upper sieve plate 3. The concentrated particles pass through the particle dispersion plate 9, which includes two symmetrical left and right sides. The wing plates have an obtuse angle at the connection between the two wing plates. The height of the wing plates gradually decreases from the center to both sides, forming an arc-shaped edge. The arc-shaped edge is used to gradually disperse the particles accumulated below the particle inlet box 8 and spread them on the upper screen plate 3. During the process of the particles moving on the upper screen plate 3, qualified ions and ultrafine particles fall through the screen holes 4 to the lower screen plate 11. Ultrafine particles fall through the screen holes 4 on the lower screen plate 11 and finally enter the ultrafine particle outlet 12. Qualified particles move on the lower screen plate 11 and finally enter the qualified material outlet 13. Irregular particles continue to move on the upper screen plate 3 and enter the irregular particle outlet pipe 6 through the irregular particle collection hopper 5.

[0023] This utility model has a reasonable structure and ingenious design. It stably disperses particles during the slicing and screening process, preventing particle accumulation at the particle inlet box when the granulation speed is high. This ensures the continuity of the granulation process, effectively reduces costs, increases the quantity of qualified products, and improves enterprise efficiency. It solves the technical problems of existing vibrating screens, such as particle accumulation at the particle inlet box and particle concentration on the upper screen plate, which leads to granulation interruption and the mixing of qualified particles with irregularly shaped particles, increasing costs and seriously affecting production efficiency. Compared with existing technologies, it has a very good market prospect and development space.

However, the present invention is not limited to the above embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the concept of the present invention.
