Description

Technical Field

[0001] This utility model relates to the field of flame retardant production technology, specifically to a granulator for flame retardant production. Background Technology

[0002] Flame retardants are functional additives that impart flame-retardant properties to flammable polymers. They are mainly designed for flame retardancy of polymer materials. There are many types of flame retardants, which are classified into additive flame retardants and reactive flame retardants according to their application methods. At the end of the flame retardant production and processing process, the cured flame retardant needs to be cut and granulated to obtain the finished flame retardant particles.

[0003] For example, patent application number 202420708321.6 discloses a granulator for producing flame retardants. This utility model discloses a granulator for producing flame retardants, belonging to the field of flame retardant production technology. It includes a granulator body, a feed hopper at the top of the granulator body, a screening component at the top and middle of the granulator body, a dust collection component on one side of the granulator body, a discharge component at the bottom of the granulator body, and a collection component at the discharge port of the granulator body. This utility model also includes a support frame. The device includes a screening seat, sealing plate, screen, elastic seat, return spring, top rod, rotating rod, and screening motor, which facilitates the screening of chopped flame retardant, separating larger particles. A clamping seat, clamping rod, clamping slider, and clamping spring are included to pull out the screening seat and remove the flame retardant from the screen. A collection trolley is also included for easy collection and transfer of the granulated flame retardant. However, in the granulation machine used for this flame retardant production, there is a risk that flame retardant particles may become stuck on the filter screen after screening. Existing screening devices require removing these particles from the granulator for cleaning.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings and proposed a granulator for flame retardant production. Utility Model Content

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1-2 As shown, a granulator for producing flame retardants includes a granulator body 1 with a feed inlet 101 on its upper surface, a dust removal device 102 on the upper front surface of the granulator body 1, a discharge outlet 103 on the lower front surface of the granulator body 1, a support frame 2 below the discharge outlet 103, a support plate 201 on the surface of the support legs of the support frame 2, and a drive motor 202 mounted on the upper surface of the support plate 201. The advantage of this configuration is that flame retardants can be produced and processed through the granulator body 1.

[0017] Furthermore, a limiting slide bar 203 is provided on the inner wall surface of the support frame 2, and a return spring 204 is provided on the outer surface of the end of the limiting slide bar 203. The advantage of this setting is that by setting the limiting slide bar 203, the movement of the support frame 205 can be restricted, so as to screen the flame retardant particles on the surface of the filter screen 206 and reduce the flame retardant particles stuck on the surface of the filter screen 206.

[0018] Furthermore, a support frame 205 is slidably mounted on the outer surface of the limiting slide bar 203, and a filter screen 206 is provided on the bottom surface of the support frame 205. The advantage of this arrangement is that the flame retardant particles can be screened through the filter screen 206.

[0019] Furthermore, a force-bearing plate 207 is provided on the lower surface of the support frame 205, and the force-bearing plate 207 is connected to the drive motor 202 in contact. The advantage of this arrangement is that, through the setting of the drive motor 202, the support frame 205 can be driven to shake back and forth on the inner surface of the support frame 2 by impact, so as to screen out unqualified flame retardant particles. At the same time, the shaking method can also prevent flame retardant particles from getting stuck inside the filter screen 206, reducing the number of times the filter screen 206 needs to be replaced.

[0020] like Figures 3-4 As shown, a sliding rod 301 is slidably installed on the inner surface of the support frame 205, and a compression spring 302 is provided on the outer surface of the sliding rod 301. The advantage of this arrangement is that, through the setting of the compression spring 302, the sliding rod 301 can be driven to slide into the interior of the positioning hole 3 to fix the support frame 205, so as to facilitate the quick disassembly and assembly of the filter screen 206 and facilitate the cleaning and maintenance of the filter screen 206.

[0021] Furthermore, a connecting plate 303 is provided on the end surface of the sliding rod 301, and a pull handle 304 is provided on the surface of the connecting plate 303. The advantage of this setting is that by pulling the handle 304, it is easy to pull the sliding rod 301 out of the positioning hole 3, and it is also easy to lift the support frame 205.

[0022] Furthermore, the inner surface of the support frame 2 is provided with a positioning hole 3, and the positioning hole 3 and the limiting slide rod 203 are configured to slide together. The advantage of this configuration is that the positioning hole 3 facilitates the positioning and installation of the limiting slide rod 203.

[0023] Working Principle: When using the granulator produced with this flame retardant, the raw material is first fed into the granulator body 1 through the feed inlet 101 for processing. Simultaneously, the dust removal device 102 removes dust from the raw material. The processed flame retardant granules are discharged through the discharge outlet 103, falling into the support frame 2. After the flame retardant granules fall into the filter screen 206, the drive motor 202 is started to rotate, striking the force plate 207 on the lower surface of the support frame 205, causing it to slide along the limit slide bar 203. Simultaneously, after sliding, the return spring 204 pulls it back to its original position. This process repeats to remove unqualified flame retardant granules, while qualified material is removed from the filter screen 206. When the filter screen 206 needs maintenance, the sliding rod 301 connected to the connecting plate 303 can be pulled out of the positioning hole 3 by simultaneously pulling the handle 304. Then, the filter screen 206 with the support frame 205 can be removed from the support frame 2 by pulling the handle 304 to replace the filter screen 206. This is the working principle of the granulator for producing the flame retardant.
