Description

Technical Field

[0001] The utility model relates to the technical field of calcium-zinc stabilizer processing, in particular to the technical field of a screening device for processing calcium-zinc composite stabilizers.

Background Art

[0002] Calcium-zinc stabilizers are synthesized by using calcium salts, zinc salts, lubricants, antioxidants, etc. as main components through a special composite process. It can not only replace toxic stabilizers such as lead-cadmium salts and organotin compounds, but also has quite good thermal stability, light stability, transparency and coloring power.

[0003] In the production process of calcium-zinc stabilizers, after the synthesis of calcium-zinc stabilizers, dehydration drying and pulverization are required to obtain powdery powder stabilizers. To ensure that the particle size of the powder meets the requirements, a rotary sieve is needed to filter it and separate larger-volume particles. The traditional rotary sieve mesh device cannot effectively separate the large-volume particles remaining on the sieve during the filtering process, resulting in more and more large-volume particles accumulating on the sieve, blocking the mesh holes, and greatly reducing the filtering efficiency, which is not suitable for continuous production.

[0004] To solve the technical problems proposed in the background art, for example, the patent application No. CN201821580857.5 discloses a rotary sieve mesh device for the production of calcium-zinc stabilizers, including a housing. The top of the housing is provided with an upper cover, and the left and right sides of the top of the upper cover are symmetrically provided with feed inlets. The bottom of the housing is provided with a base, and outer baffles and inner baffles are provided on the left and right sides of the top of the base. By installing a vibrator on the top of the rotary sieve, the sieve mesh of the rotary sieve can generate vibration during the filtering process, separating the large-particle defective calcium-zinc stabilizers stuck in the sieve mesh gaps from the sieve mesh, and through the centrifugal action of the rotary sieve, they fall into the defective product discharge port for collection, enabling continuous screening work. However, this device still has the following defects:

[0005] 1. Although this device uses vibration to screen the materials, during the screening process of the vibrating sieve, the size of the fine particles is very easy to be similar to the size of the sieve holes, resulting in the fine particles being unable to pass through the sieve holes and being blocked on the sieve mesh, which will affect the continuity and efficiency of the entire screening process.

[0006] 2. Although this device separates the materials of large and small particles, the large particles left after screening need to be manually collected, reprocessed and then screened, which is time-consuming and laborious.

Content of the Utility Model

[0007] The purpose of the utility model is to solve the problems in the prior art, and propose a screening device for processing calcium-zinc composite stabilizers, which can improve the screening efficiency, avoid the materials being blocked on the sieve mesh during the screening process, and pulverize the large particles left after screening, without manual processing.

[0008] To achieve the above object, the utility model provides a screening device for processing calcium-zinc composite stabilizer, which includes a frame, columns, chutes, sliders, a screening frame, a screen, a processing table, supporting feet, a rotating mechanism, a rotating disk, a rotating motor, a chain, a supporting rod, and a connecting plate. The frames are symmetrically arranged up and down. Four columns are arranged at the corners between the two frames. Chutes are symmetrically opened above one of the frames. Sliders are slidably arranged in both of the two chutes. The screening frame is jointly connected above the two sliders. A screen is installed inside the screening frame. A processing table is connected to the side wall of one of the frames. Four supporting feet are arranged below the processing table. A rotating mechanism for cooperating with the screening frame is arranged above the processing table. The rotating mechanism includes a rotating disk, a rotating motor, a chain, a supporting rod, and a connecting plate. There are two rotating disks, and both of the two rotating disks are rotatably arranged above the processing table. The rotating motor is arranged below the processing table. The output end of the rotating motor penetrates above the processing table and is connected to one of the rotating disks. The outer walls of the two rotating disks are jointly sleeved with a chain. There are two supporting rods, and the two supporting rods are respectively arranged above one of the frames and above one of the rotating disks. The two supporting rods are connected by a connecting plate.

[0009] Preferably, the screen is slightly inclined downward.

[0010] Preferably, a material receiving box is arranged directly below the screen, and the material receiving box is located inside the frame.

[0011] Preferably, a discharge port is arranged on the inner side wall of the screening frame, and a discharge pipeline is arranged on the outer side wall of the screening frame. The discharge port is communicated with the discharge pipeline, and a control valve is equipped on the discharge pipeline.

[0012] Preferably, a crushing box is arranged below the discharge port of the discharge pipeline, and a crushing mechanism is arranged inside the crushing box.

[0013] Preferably, the crushing mechanism includes a crushing motor, a rotating shaft, and crushing blades. The crushing motor is arranged on the outer side wall of the crushing box. The rotating shaft is arranged on the inner side wall of the crushing box. The output end of the crushing motor penetrates the side wall of the crushing box and is connected to the rotating shaft. Several crushing blades are installed on the outer wall of the rotating shaft.

[0014] The beneficial effects of the utility model:

[0015] 1. The utility model, through the combined use of a chute, a slider, a screening frame, a screen mesh, a processing table and a rotating mechanism, can improve the screening efficiency. First, the material to be screened is poured into the screening frame. Subsequently, the rotating motor is started by an external power source. The rotating motor drives one of the rotating disks to rotate, and the rotating disk drives the other rotating disk to rotate through a chain, thereby driving the support rod on the rotating disk to rotate. During the rotation of the support rod, the support rod on the screening frame is driven to move through the connecting plate, thereby driving the screening frame to perform reciprocating motion back and forth, causing the slider below the screening frame to slide reciprocally in the chute, and then screening the material on the screen mesh. Due to the high-speed reciprocating motion of the screen mesh, the normal-sized particulate material falls into the material receiving box through the screen holes, while the larger-sized particulate material remains on the screen mesh. Through the high-speed reciprocating motion of the screen mesh, the material is not easily blocked on the screen mesh during the screening process, thereby improving the screening quality, and solving the problem that in the screening process of a vibrating screen, the size of fine particles is easily similar to the size of the screen holes, resulting in the fine particles being unable to pass through the screen holes and being blocked on the screen mesh.

[0016] 2. The utility model, through the combined use of a discharge pipeline, a crushing box and a crushing mechanism, can automatically complete the crushing. After the screening of the material on the screen mesh is completed, the control valve is opened, so that the larger-sized particulate material on the screen mesh rolls into the discharge port through the movement of the screen mesh and falls into the crushing box through the discharge pipeline. Then the box cover is closed, and subsequently the crushing motor is started. The crushing motor drives the rotating shaft to rotate, and the rotating shaft drives the crushing blades to rotate, thereby performing crushing treatment on the material inside the crushing box, thus avoiding manual collection and manual processing, saving time and effort, and having high work efficiency, and solving the problem that the large particles left after screening need to be manually collected and reprocessed and then screened, resulting in being time-consuming and laborious.

The two support rods 94 are respectively arranged above one of the frames 1 and above one of the rotating disks 91. The two support rods 94 are connected by a connecting plate 95. By starting the rotating motor 92 through an external power source, the rotating motor 92 drives one of the rotating disks 91 to rotate. The rotating disk 91 drives the other rotating disk 92 to rotate through the chain 93, and then drives the support rod 94 on the rotating disk 92 to rotate. During the rotation of the support rod 94, the support rod 94 on the screening frame 5 is driven to move through the connecting plate 92, and then drives the screening frame 5 to perform reciprocating motion back and forth, so that the slider 4 below the screening frame 5 slides back and forth in the chute 3, and then screens the materials on the sieve mesh 6. Due to the high-speed back-and-forth movement of the sieve mesh 6, the materials are not easily blocked on the sieve mesh 6 during the screening process, thereby improving the screening quality.

[0023] Refer to Figure 1, for a screening device for processing calcium-zinc composite stabilizer of the present utility model, the screen 6 is arranged to be slightly inclined downward, which can facilitate the rolling of larger particle materials into the discharge port 51.

[0024] Refer to Figure 1 , for a screening device for processing calcium-zinc composite stabilizer of the present utility model, a receiving box 10 is arranged directly below the screen 6, and the receiving box 10 is located within the frame 1, so that the screened materials can fall into the receiving box 10, facilitating subsequent unified processing.

The discharge port 51 is communicated with the discharge pipe 52, and a control valve is equipped on the discharge pipe 52. Through the control of the control valve, larger particle materials can fall into the crushing box 11 through the discharge pipe 52 for processing.

When the crushing motor 122 drives the rotating shaft 123 to rotate, the rotating shaft 123 drives the crushing blades 124 to rotate, thereby crushing the materials inside the crushing box 11.

[0028] The working process of the present utility model:

[0029] During the operation of a screening device for processing a calcium-zinc composite stabilizer according to the present utility model, first, the material to be screened is poured into the screening frame 5. Subsequently, the rotating motor 92 is started by an external power source. The rotating motor 92 drives one of the rotating disks 91 to rotate. The rotating disk 91 drives the other rotating disk 91 to rotate through the chain 93, thereby driving the support rod 94 on the rotating disk 91 to rotate. During the rotation process, the support rod 94 drives the support rod 94 on the screening frame 5 to move through the connecting plate 95, thereby driving the screening frame 5 to perform a reciprocating motion back and forth. As a result, the slider 4 below the screening frame 5 slides back and forth in the chute 3, thereby screening the material on the sieve mesh 6. Due to the high-speed back-and-forth movement of the sieve mesh 6, the normal granular material falls through the sieve holes into the receiving box 10, while the larger granular material remains on the sieve mesh 6. When the screening of the material on the sieve mesh 6 is completed, the control valve is opened, so that the larger granular material on the sieve mesh 6 rolls into the discharge port 51 through the movement of the sieve mesh 6 and falls into the crushing box 11 through the discharge pipeline 52. Then, the box cover is closed. Subsequently, the crushing motor 122 is started. The crushing motor 122 drives the rotating shaft 123 to rotate. The rotating shaft 123 drives the crushing blades 124 to rotate, thereby performing a crushing process on the material inside the crushing box 11. This avoids manual collection and manual processing, saves time and effort, and has high work efficiency.

The wiring diagram of the power element and the power supply are common knowledge in the art. And the present utility model is mainly used to protect mechanical devices, so the control mode and wiring arrangement of the present utility model will not be explained in detail.
