Description

Technical Field

[0001] The utility model relates to the technical field of expanded perlite particle screening, and more specifically, to an expanded perlite particle screening device. Background Art

[0002] In the existing field of expanded perlite particle screening technology, the commonly used screening devices have obvious technical limitations. These devices usually only use a single large-sized screen for screening operations, and the entire screening system only contains two layers of screening structure. This simple layered design cannot meet the needs of fine grading of perlite particles. At the same time, due to the limitations of the screening mechanism design, the screen can only perform screening operations on the horizontal plane, lacking multi-angle and multi-directional screening functions.

[0003] This traditional plane screening method causes the perlite particles to easily accumulate and stick together during the screening process, greatly reducing the screening efficiency and accuracy. Due to the lack of a three-dimensional screening structure and a reasonable vibration mechanism, some particles cannot be fully dispersed, resulting in uneven screening and inaccurate grading. This not only affects the quality of the specification division of the pearlite particles, but also significantly reduces production efficiency and cannot meet the requirements for fine grading of perlite particles in modern industrial production.

[0010] The utility model is further configured such that rounded corners are respectively provided on both sides of the two bidirectional blocks, and adjusting bolts are provided on the internal threads of the two bidirectional blocks.

[0013] Compared with the prior art, the utility model provides an expanded perlite particle screening device, which has the following beneficial effects:

[0014] 1. The grading mechanism forms a multi-stage screening structure system through the combined design of the outer shell and multiple intermediate shells. The inclined screen plate in each intermediate shell constructs a three-dimensional screening space. The multiple screening holes with increasing sizes on the screen plate provide accurate grading capabilities. The setting of the discharge port enables materials of different specifications to be diverted and output in time. The extended design of the discharge port ensures the smooth discharge of waste materials. This multi-level and multi-angle grading design greatly improves the screening efficiency and grading accuracy of expanded perlite particles.

[0015] 2. The supporting mechanism adopts an innovative combination of a symmetrical plate and a socket. The flexible adjustment of the overall structure is achieved through the rotational connection between the symmetrical plate, the outer shell and the fixed seat. The cooperation between the insertion rod sliding in the insertion hole and the fitting disk ensures the stability of the supporting structure. The spring design between the two-way blocks provides the necessary buffering effect. The rounded corner design reduces mechanical wear. The precise cooperation between the adjusting bolt and the limit ring realizes the adjustment of the angle. This supporting structure with multiple protections and precise adjustment significantly improves the adaptability and service life of the equipment.

[0016] 3. The vibration mechanism tightly connects the vibration motor and the casing through the connecting seat, realizing efficient transmission of vibration force. The design of the connecting seat not only ensures the stability of vibration, but also improves the controllability of vibration frequency. The coordinated cooperation between the output of the vibration motor and the overall structure significantly enhances the screening effect. This simple and efficient vibration design provides continuous and stable power support for the entire screening system. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In this embodiment, when screening is performed, the expanded perlite particles are placed in the outer shell 2. At this time, the angle of the outer shell 2 can be adjusted to adapt to the corresponding screening requirements, and then the vibration motor 19 is started, so that the vibration can be transmitted to the outer shell 2, and then the expanded perlite particles are screened, first entering the first screening plate 4.

Since the adjusting bolt 16 is threadedly connected to the two-way block 13 and the adjusting bolt 16 is against the limit ring 17, the distance between the two two-way blocks 13 can be changed, thereby driving the position of the two symmetrical plates 8 to change, thereby changing the angle of the shell 2 to adapt to the corresponding screening requirements.

Through vibration, not only screening is performed, but also the remaining materials can be vibrated into the next intermediate shell 3, and then respectively The material is discharged through the discharge port 5, thus completing the screening process, and finally the slag is discharged through the discharge port 7, thereby completing the whole process. The spring 14 during vibration can avoid the rigid connection with the fixed frame 1. When the inclination angle of the shell 2 needs to be adjusted according to different situations, the adjusting bolt 16 is first rotated. Since the adjusting bolt 16 is threadedly connected to the two-way block 13 and the adjusting bolt 16 is against the limit ring 17, the distance between the two two-way blocks 13 can be changed, thereby driving the position of the two symmetrical plates 8 to change, thereby changing the angle of the shell 2 to adapt to the corresponding screening requirements.
