Description

Technical Field

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

[0002] Flame retardants, as functional additives, primarily improve the safety of flammable polymers such as plastics, rubber, and fibers by preventing, delaying, or terminating flame propagation, thereby imparting flame-retardant properties. Since raw materials may contain impurities such as lumps and fibers, which directly affect the purity and performance stability of flame retardants, linear vibrating screens are often used for coarse screening of raw materials during production to remove large particles and ensure the quality of raw materials for subsequent processes.

[0003] In the coarse screening process of flame retardant raw materials, existing linear screening machines typically have dust covers installed on top of the equipment to suppress dust spillage in order to meet environmental protection requirements. Currently, most dust covers are connected to the screen body by bolts. Although this structure can ensure sealing, in actual production, when it is necessary to replace the screen, all the fixing bolts must be removed before the dust cover can be opened to replace the screen. This makes the screen replacement operation cumbersome and time-consuming, affecting the efficiency of equipment maintenance. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a raw material screening machine for flame retardant production, making screen replacement simpler and more convenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a raw material screening machine for flame retardant production, comprising a linear screening machine body, a vibration motor installed at the bottom of the linear screening machine body, a maintenance window opened on one side of the linear screening machine body, a maintenance plate installed inside the maintenance window, fish-tail bolts slidably connected to the four corners of the maintenance plate, the fish-tail bolts being threadedly connected to the linear screening machine body, and a screen slidably connected inside the linear screening machine body.

[0006] Furthermore, multiple handles are fixedly attached to the side of the inspection plate away from the main body of the linear screening machine, and the handles are evenly distributed.

[0007] Furthermore, the main body of the linear screening machine has symmetrically arranged sliding grooves at the upper and lower ends near the maintenance window. The sliding grooves are connected to the maintenance window and are L-shaped. A slider is slidably connected inside the sliding groove and is fixedly connected to the maintenance plate.

[0008] Furthermore, the main body of the linear screening machine is internally fixed with equally spaced crossbeams, and a connecting frame is slidably connected to the top of the crossbeams, with the screen fixed to the top of the connecting frame.

[0009] Furthermore, the bottom of the connecting frame is fixed with multiple equidistant connecting blocks, and the top of the crossbeam is provided with connecting grooves that match the connecting blocks.

[0010] Compared with the prior art, the present invention has the following beneficial effects: When the screen of this raw material screening machine for flame retardant production needs to be replaced, simply remove the fish-tail bolts, then push the inspection plate horizontally to align the slider with the outlet position of the chute, and then pull the inspection plate away from the main body of the linear screening machine to remove the inspection plate. Then, pull the connecting frame and the screen out of the main body of the linear screening machine together to replace the screen. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Please see Figure 1-5 A raw material screening machine for flame retardant production includes a linear screening machine body 1, a vibrating motor installed at the bottom of the linear screening machine body 1, a maintenance window 2 opened on one side of the linear screening machine body 1, a maintenance plate 4 installed inside the maintenance window 2, and fish-tail bolts 12 slidably connected to the four corners of the maintenance plate 4. The fish-tail bolts 12 are threadedly connected to the linear screening machine body 1, and a screen 11 is slidably connected inside the linear screening machine body 1.

[0015] When the screen 11 needs to be replaced in the raw material screening machine for flame retardant production of this utility model, it is only necessary to first remove the fish-tail bolt 12, then remove the inspection plate 4 from the main body 1 of the linear screening machine, then pull the screen 11 out of the main body 1 of the linear screening machine, insert a new screen 11, and then put the inspection plate 4 back in the position of the inspection window 2 and fix it with the fish-tail bolt 12. The whole process does not require disassembling the heavy dust cover, which improves the replacement efficiency of the screen 11. When the main body 1 of the linear screening machine is working normally, the vibrating motor will drive the screen 11 to vibrate. The material enters from the feed port of the main body 1 of the linear screening machine and is thrown up and jumps forward on the screen 11. Grading can be achieved by passing through multiple screens 11. In addition, the main body 1 of the linear screening machine and the vibrating motor in this utility model are existing mature products, so they will not be described in detail here.

[0016] like Figure 1 and Figure 2 As shown, multiple handles 6 are fixedly attached to the side of the inspection plate 4 away from the main body 1 of the linear screening machine, and the handles 6 are evenly distributed.

[0017] Specifically, it is more convenient to move the inspection plate 4 using the handle 6.

[0018] like Figure 2 , Figure 3 and Figure 5 As shown, the main body 1 of the linear screening machine has symmetrically arranged sliding grooves 3 at the upper and lower ends near the inspection window 2. The sliding grooves 3 are connected to the inspection window 2. The sliding grooves 3 are L-shaped. A slider 5 is slidably connected inside the sliding grooves 3. The slider 5 is fixedly connected to the inspection plate 4.

[0019] Specifically, when installing the inspection plate 4, the slider 5 can be placed into the slide 3 from the end of the slide 3 away from the main body 1 of the linear screening machine until the slider 5 abuts against the side wall of the slide 3. Then, the inspection plate 4 is pushed so that the slider 5 moves to the other end of the slide 3. This completes the initial fixing of the inspection plate 4, so that the inspection plate 4 can be reinforced with the fish-tail bolts 12 later.

[0020] like Figure 2 , Figure 3 and Figure 4 As shown, the main body 1 of the linear screening machine is internally fixed with equally spaced crossbeams 7, and a connecting frame 9 is slidably connected to the top of the crossbeams 7. The screen 11 is fixedly connected to the top of the connecting frame 9.

[0021] Specifically, the screen 11 is fixed to the connecting frame 9 by welding or bolting, so that the screen 11 is not easily bent or damaged when it is pulled out.

[0022] like Figure 2 , Figure 3 and Figure 4As shown, the bottom of the connecting frame 9 is fixed with multiple equally spaced connecting blocks 10, and the top of the crossbeam 7 is provided with a connecting groove 8 that matches the connecting blocks 10.

[0023] Specifically, the connecting frame 9 is connected and fixed to the crossbeam 7 via the connecting block 10 and the connecting groove 8, which makes the installation and disassembly of the connecting frame 9 simple and convenient. In addition, it is worth noting that: the number of crossbeams 7 is small and will not obstruct the screen 11 over a large area, so the screening effect of the screen 11 will not be affected. Moreover, the screen connecting frame 9 is located on top of the crossbeam 7, which blocks the connecting groove 8, so the material will not enter the connecting groove 8 and cause the connecting frame 9 to be stuck. At the same time, a padding layer, such as a rubber layer, can be added to the bottom of the connecting frame 9 or the top of the crossbeam 7 to seal the gap between the connecting frame 9 and the crossbeam 7 and prevent impurities from entering the connecting groove 8.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
