Description

Technical Field

[0001] This utility model relates to the field of industrial technology, specifically to a high-efficiency rotary sieving device for the production of epoxy polyester plastic powder. Background Technology

[0002] The process of separating loose materials into different grades by passing them through one or more screens is called screening. A screening machine uses the movement of materials and equipment to allow the desired portion of the material to pass through the screen holes, while filtering and separating the unwanted material, and collecting the desired material after screening.

[0003] Currently, most vibrating screens on the market are vibrating screens. These machines use a vibrating rotor to vibrate the entire equipment, allowing materials to pass through the screen for filtration. However, if the material is too large or too tightly packed, it may cause screening abnormalities. Furthermore, prolonged vibration can affect the tightness of internal parts, requiring frequent maintenance or replacement, which can lead to delays in operations. If maintenance is not carried out effectively or replacement is neglected for a long time, it may even cause serious machine malfunctions, such as internal misalignment leading to machine damage.

[0018] This utility model has the following beneficial effects:

[0019] (1) The present invention is designed to separate the feeding amount and the stirring space. The top is designed with a feeding port, a handle and a top cover. It is convenient for maintenance and inspection before and after production. The visible range is large. When starting the operation, it can be pre-started according to the production needs. The difference is that the crushing and screening of the feeding can be carried out faster during the operation. Considering that there may be lumps or clumps in the feeding, the hammer of the internal stirring mechanism can be rotated to crush them. According to the different sizes of the feeding, there is a bottom pushing device to push. The rotating hammer can also turn the material over while breaking it.

[0020] (2) According to the size of the crushed material, the material is pushed by the pusher to pass through the filter screen and enter the next stage. Since it is a blunt instrument for crushing, it will be more thorough than cutting and crushing during the crushing process. During operation, due to the influence of centrifugal force and gravity, the crushing force applied by the hammer will become stronger. It should be noted that if the material is too hard, such as ore or stone, it is not recommended to put too much in at one time. As there are two storage bins, the operation of the equipment can be adjusted according to the production needs.

[0021] (3) This utility model is a rotary screen. Compared with the vibrating or resonant screen, it has a more straightforward structure and is easier to maintain and clean in the later stage. It is more stable in production and use. The motor drives the equipment to operate. The parts are linked together in operation, which makes the equipment run more stably. Different stirring mechanisms cause the material to be put in with different degrees of dryness and wetness, thus reducing the impact on operation.

[0022] (4) Compared with the vibrating screen, the long-term vibration may cause misalignment between the equipment, while the rotary screen avoids this situation to the greatest extent. When materials are fed in, or when large-volume materials are fed in, the vibrating screen may experience abnormal operation. In this invention, the hammer-type operation mode is adopted, which avoids the abnormal situation that may be encountered to a certain extent.

[0023] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0048] A protruding transmission plate 609 is rotatably connected to the side of the T-shaped rotating block 608 away from the protruding rod 607.

This design is to ensure that the material pushing structure can be linked to affect the material during the operation of the stirring structure, so as to achieve a better separation and crushing effect of the material.

[0049] The top of the coarse material silo shell 401 is provided with a top cover 7. The top cover 7 includes a top cover plate 701 rotatably connected in a square groove at the top of the coarse material silo shell 401. The top cover plate 701 is fixedly connected to a top cover plate 701 inlet 702 on the side away from the coarse material silo shell 401, which is in communication with the top cover plate 701. The top of the top cover plate 701 is fixedly connected with two handles 703. This design is for the purpose of inspecting and maintaining the equipment before and after operation, and can observe the internal condition of the coarse material silo to a large extent, as well as whether there are any abnormalities in operation.

[0050] Before use, first open the top cover 7, check the internal condition of the coarse material hopper 4, confirm the equipment's orientation and the stability of the installation structure, and then feed the required material into the coarse material hopper shell 401 through the feed inlet 702. (Note that if a large amount needs to be fed at once, the equipment can be pre-started to achieve better crushing and screening effects.)

[0051] The motor 102 is started, and the output end causes the drive gear 103 to operate. It drives the rotating shaft 104 so that the T-shaped hammer 504 and the material hammer 505 in the stirring structure 5 crush and disperse the input material. Then, the convex transmission plate 609 in the linked pushing structure 6 slides along the groove on the outer surface of the cam 503.

[0052] Specifically, depending on the different positions of the chute, the convex transmission plate 609 is pushed to affect the T-shaped rotating block 608, thereby driving the convex rod 607, causing the transmission rod 602 to rotate back and forth, which in turn causes the rotating block 603 to work in conjunction with the scraper 604 to push the affected material.

[0053] When the motor 102 operates at its output end, the driving gear 103, driven by several meshing secondary gears, causes the top block 202 inside the limiting cover 201 in the transmission structure 2 to slide, rotating the rocker 203. This stores the force of the compression spring 205. Once the secondary gears rotate, the stored force is released by the compression spring 205, causing the impact pin 206 to slide and displace, applying an impact force to the entire fine material bin 3. This causes the filter screen 402 on top of the fine material bin 3 to vibrate, further facilitating the screening of the affected material.

[0054] Both the fine material bin 3 and the coarse material bin 4 have corresponding discharge ports connected to their outer surfaces. The discharge ports collect the required materials according to the material conditions in the bins, so as to meet the needs of the next production step.

[0055] During the use of the equipment, adjustments should be made according to the production requirements. Before and after starting the equipment, the top cover 7 should be opened in time to clean the internal coarse material bin. Due to the presence of the shaft housing 302, it should be sealed properly during cleaning. The shaft housing 302 is driven to rotate by the motor output end and then discharged from the fine material outlet 303.
