Description

Technical Field

[0001] This utility model relates to the field of pigment production equipment, and more specifically, it relates to a vibrating screen. Background Technology

[0002] In pigment production, vibrating screens are crucial screening equipment, primarily used to classify pigment particles of different sizes to ensure product particle size uniformity. Traditional vibrating screens typically consist of a screen box, screen mesh, vibrating motor, and elastic support device. Their working principle involves the excitation force generated by the vibrating motor causing the screen box to vibrate periodically, resulting in a throwing motion of the material on the screen surface, thus achieving particle classification and screening. To improve screening efficiency, vibrating screens usually employ a multi-layer screen design, with each layer having an independent discharge port below. Pigment powders of different particle sizes are guided to designated collection devices via inclined discharge pipes. However, this structure has a significant problem: because the discharge pipe is rigidly connected to the vibrating screen body, it vibrates along with the screen body during operation. This synchronous vibration causes deviations in the connection between the discharge pipe and the downstream collection device due to relative movement. Fine pigment powder can escape into the working environment due to these deviations and the kinetic energy of the powder itself. Pigment powders generally have the characteristics of small particle size and light weight. In particular, the particle size of high-end organic pigments and some inorganic pigment powders is usually in the micrometer range, making them more prone to dust diffusion under vibration conditions.

[0005] The present invention is further configured such that: a plurality of pull rings are fixedly connected to the outer side wall of the elastic ring, and the plurality of pull rings are arranged in a circumferential array on the outer side wall of the elastic ring.

[0006] The present invention is further configured such that the lowest point of the counterweight block is on the same plane as the bottom surface of the support.

[0007] The present invention is further configured such that the top of the counterweight is formed into a conical structure.

[0012] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0013] Example: A vibrating screen, such as Figure 1 As shown, the main components include a support frame 1, a housing 2, springs 3, and a vibrating motor 4. A dust collection structure is installed at the end of the discharge pipe 5. The support frame 1 serves as the mounting foundation for the entire equipment, with four springs 3 supporting the housing 2 above it. A screen is installed inside the housing 2 for classifying and screening pigment particles of different sizes. Two vibrating motors 4 are symmetrically installed at the bottom of the side wall of the housing 2. During operation, they generate excitation force, causing the housing 2 and the internal screen to vibrate periodically, prompting the material to be thrown across the screen surface for efficient screening. A discharge pipe 5 is located on the side wall of the housing 2, through which the screened material is discharged.

[0014] like Figure 1 , Figure 2 , Figure 3As shown, a cloth sleeve 6 is detachably connected to the bottom end of the discharge pipe 5. The cloth sleeve 6 is made of polyester yarn, which has good stiffness and abrasion resistance, and can reduce the impact of vibration on powder flow caused by wrinkles in the cloth sleeve 6. A rubber elastic ring 7 is fixed to the top of the cloth sleeve 6. The elastic ring 7 is tightly fitted on the outer wall of the discharge pipe 5 and is limited by an integrally formed protruding ring 8 on the discharge pipe 5. The diameter of the protruding ring 8 is larger than the diameter of the elastic ring 7 to ensure a stable connection of the cloth sleeve 6. Several pull rings 11 are also provided on the outer wall of the elastic ring 7 to facilitate pulling the elastic ring 7 to change its diameter, thereby realizing the installation and removal of the cloth sleeve 6.

[0015] like Figure 1 , Figure 2 As shown, the bottom end of the cloth sleeve 6 is circumferentially connected with several straps 9. The straps 9 are made of elastic material, allowing them to adaptively adjust their length during vibration and preventing deformation of the cloth sleeve 6 due to rigid tension. A counterweight 10 is fixed to the end of each strap 9. Under normal conditions, the straps 9 undergo slight stretching deformation under the pull of the counterweight 10, ensuring that the lowest point of the counterweight 10 and the bottom surface of the support base 1 are on the same plane. In actual use, the receiving cylinder for receiving raw material powder is placed below the discharge pipe 5, and the counterweight 10 is placed on the inner bottom surface of the receiving cylinder. The cloth sleeve 6 hangs down into the receiving cylinder under the pull of the straps, but the cloth sleeve 6 itself does not contact the bottom of the cylinder, preventing powder from accumulating inside the cloth sleeve 6 and affecting subsequent powder discharge. The top of the counterweight 10 is designed with a conical structure to minimize powder carried out by the counterweight 10 when the straps 9 pull it out during the removal of the receiving cylinder.

[0016] When the vibrating screen is working, the vibrating motor 4 drives the housing 2 and the discharge pipe 5 to vibrate synchronously. However, because the cloth sleeve 6 is flexibly connected by the elastic ring 7, and the counterweight 10 provides inertial stability inside the receiving cylinder, the vibration amplitude of the cloth sleeve 6 is significantly reduced, and the bottom end of the cloth sleeve 6 is always located inside the receiving cylinder, thereby effectively reducing powder dispersion. After the powder enters the cloth sleeve 6 from the discharge pipe 5, it slides down along the inner wall of the cloth sleeve 6 under the action of gravity and enters the receiving cylinder through the outlet formed by the strap 9. The elasticity of the strap 9 allows the receiving cylinder to move within a certain range without affecting the collection effect, improving operational flexibility.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
