Technical Field

[0001] The utility model relates to the technical field of flame retardant granule production, in particular to a production device for high-efficiency flame retardant granules. Background Technique

[0002] Flame retardant granules are granular substances with flame retardant functions, also known as flame retardant granules or fireproof granules. Flame retardant granules are mainly divided into several categories such as bromine-based / halogen-based, phosphorus-based, nitrogen-based, and inorganic flame retardant granules. Among them, bromine-based / halogen-based flame retardant granules are one of the most excellent flame retardant products in current plastics and rubbers and other resins.

[0003] Flame retardant granules are granular products obtained by the organic combination, modification treatment, and synergistic effect of various flame retardant components on the basis of flame retardants, and through mixing, extrusion, and granulation by a twin-screw or triple-screw extruder; in the production process of flame retardant granules, the cooling pool is a key device, which closely cooperates with the extruder to quickly reduce the temperature of the hot granules extruded from the extruder. However, there is a significant technical problem in the existing design of the cooling pool, that is, the water in the cooling pool is prone to adhering to impurities in the workshop air, such as dust, fibers, and other fine particles. These impurities adhere in the cooling pool and have an adverse effect on the raw materials of the flame retardant granules being cooled.

[0004] Therefore, the utility model provides a production device for high-efficiency flame retardant granules to solve the above problems. Content of the Utility Model

[0005] The utility model provides a production device for high-efficiency flame retardant granules, aiming to solve the problem that the existing cooling pool is easily affected by impurities and has an impact on the raw materials of flame retardant granules proposed in the background technique.

[0006] To achieve the above object, the utility model provides the following technical solution: A production device for high-efficiency flame retardant granules, including a bracket, a water pool fixedly installed at the top of the bracket, and a cooling pool arranged inside the water pool.

[0007] Preferably, a partition board is fixedly installed on the inner side wall of the return water tank. Openings are symmetrically formed on the top surface of the partition board. Filter meshes are fixedly installed in the openings. The bottom surface of the water pool is rotatably installed with a rotating shaft through a fixing frame.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] The present invention provides a production device for highly efficient flame-retardant particles, as Figures 1-5 shown. The production device for the flame-retardant particles includes a bracket 1, a water tank 2 fixedly installed at the top of the bracket 1, and a cooling tank 3 arranged inside the water tank 2. A return water tank 4 is fixedly installed on the bracket 1 and located directly below the water tank 2. A through hole 21 is opened on the bottom surface of the water tank 2. Four guide rollers 31 are rotatably installed in the cooling tank 3. An overflow port 32 is opened on one side of the open end of the cooling tank 3. A circulating water pump 5 is fixedly installed on the return water tank 4. The liquid inlet end of the circulating water pump 5 is communicated with the bottom end of the return water tank 4. The liquid outlet end of the circulating water pump 5 is fixedly installed with a water supply pipe 51. The end of the water supply pipe 51 away from the circulating water pump 5 extends above the cooling tank 3, so that the water in the return water tank 4 can be directly added to the cooling tank 3.

[0021] During use, the raw materials extruded by the extruder can directly pass through the cooling tank 3 and be guided by the guide rollers 31. The raw materials in the cooling tank 3 can be cooled and formed by the water therein. When the circulating water pump 5 is turned on, the water in the return water tank 4 can be added to the cooling tank 3 through the water supply pipe 51. When the water in the cooling tank 3 reaches a certain height, it can flow into the water tank 2 through the overflow port 32. The water in the water tank 2 can flow back into the return water tank 4 through the through hole 21 to realize circulation. When the water in the water tank 2 flows out through the through hole 21, due to the certain distance between the return water tank 4 and the water tank 2, the water can be naturally cooled during the flow, so as to continuously cool and shape the raw materials in the cooling tank 3.

[0022] Furthermore, a partition 41 is fixedly installed on the inner wall of the return water tank 4, an opening 42 is symmetrically opened on the top surface of the partition 41, a filter screen 43 is fixedly installed in the opening 42, and a rotating shaft 6 is rotatably installed on the bottom surface of the pool 2 through a fixed frame, and a transmission mechanism 61 is symmetrically arranged on the rotating shaft 6; when the water in the pool 2 flows back into the return water tank 4, it can flow to the bottom of the return water tank 4 through the opening 42 on the partition 41, and the filter screen 43 in the opening 42 can filter the water, so that the recycled water can be kept clean.

[0023] Specifically, the transmission mechanism 61 includes a support rod 611 rotatably mounted on the top surface of the return water tank 4 through a fixed frame, a transmission bevel gear 612 fixedly mounted on the top of the support rod 611, and a driving bevel gear 613 mounted on the rotating shaft 6 and meshing with the transmission bevel gear 612. The rotating shaft 6 is provided with an impeller 614 corresponding to the through opening 21. When water flows out along the through opening 21, it can impact the impeller 614 and drive the impeller 614 to rotate. When the impeller 614 rotates, it can synchronously drive the rotating shaft 6 to rotate. The driving bevel gear 613 on the rotating shaft 6 is meshed with the transmission bevel gear 612 on the support rod 611, thereby driving the transmission bevel gear 612 and the support rod 611 to rotate to achieve driving.

[0024] Furthermore, a cleaning plate 7 adapted to the filter screen 43 is fixedly installed at the bottom end of the support rod 611, and a make way groove 71 is provided on the side of the cleaning plate 7 opposite to the filter screen 43, and a cleaning roller 72 is rotatably installed inside the make way groove 71, and a cleaning mechanism 73 for cleaning the cleaning roller 72 is provided on one side of the cleaning plate 7; when the support rod 611 rotates, the cleaning plate 7 at the bottom end can be driven to rotate along the filter screen 43, and when the cleaning plate 7 rotates, the impurities on the filter screen 43 can be cleaned through the cleaning roller 72 on its bottom surface, thereby reducing the blockage of the filter screen 43 and ensuring the filtering effect of the filter screen 43.

[0025] More specifically, the cleaning mechanism 73 includes a connecting port 731 provided on the side wall of the cleaning plate 7, a plurality of combing teeth 732 fixedly installed on the inner bottom wall of the connecting port 731 and distributed in a linear array, and a material guide frame 733 fixedly installed on the side wall of the cleaning plate 7 and located below the connecting port 731; when the cleaning roller 72 rotates with the cleaning plate 7, it can contact the filter screen 43 and then rotate in the yield groove 71, and when the cleaning roller 72 rotates, the bristles thereon can contact the combing teeth 732 in the connecting port 731, and the impurities on the bristles can be removed by the combing teeth 732, and the impurities cleaned by the combing teeth 732 can fall into the material guide frame 733, and under the action of the centrifugal force of the rotation of the material guide frame 733, the impurities can slide along the material guide frame 733 to the edge of the filter screen 43.

[0026] It should be noted that an annular groove 44 is provided inside the opening 42 and is flush with the top surface of the filter net 43; when impurities slide to the edge position of the material guiding frame 733, they can directly enter the inside of the annular groove 44 in the opening 42, and the staff only needs to clean the inside of the annular groove 44 regularly.
