Abstract
Description
Technical Field
[0001] This utility model relates to the field of decabromodiphenyl ethane production technology, and in particular to a vibrating screening device for manufacturing decabromodiphenyl ethane masterbatch. Background Technology
[0002] Decabromodiphenyl ethane is a broad-spectrum additive flame retardant widely used in industries such as resins, rubber, coatings, adhesives, and synthetic fibers. To facilitate its later addition, decabromodiphenyl ethane is granulated into masterbatch form after production.
[0003] Currently, after decabromodiphenyl ethane is made into masterbatch, it needs to be graded and screened by vibrating screening equipment so that it can be stored separately according to different particle sizes. When using vibrating screening equipment, because its screen has a certain width, in order to improve screening efficiency, the masterbatch needs to be manually poured as dispersedly as possible into the higher end of the vibrating screening equipment. However, this method of pouring material is time-consuming and labor-intensive. Moreover, since the upper part of the screening equipment is mostly open, the dust generated during vibration can easily be inhaled by the workers who are pouring material, thus endangering their health.
[0004] To address this issue, we propose a vibration screening device for manufacturing decabromodiphenyl ethane masterbatch. Utility Model Content
[0005] The purpose of this invention is to provide a vibrating screening device for manufacturing decabromodiphenyl ethane masterbatch, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A vibrating screening device for manufacturing decabromodiphenyl ethane masterbatch includes a bottom box, a top box, a screen, a vibrating motor, and a discharge box. The screen is installed between the bottom box and the top box, and the vibrating motor is installed below the bottom box. The discharge box is installed at the lower ends of the bottom box and the top box respectively. A feed hopper is provided at the feed inlet on the top box. Folding protective covers are movably installed between the two sides of the feed hopper and the edge of the feed inlet. The bottom periphery of the feed hopper is supported by a bracket. A slide is fixed to the edge of the bracket. A reciprocating screw is threaded through and screwed into the interior of the slide. A rotary motor is installed at one end of the reciprocating screw.
[0008] In a further embodiment, a partition is slidably installed inside the discharge port of the feed hopper, and one end of the partition extends out of the outer wall of the feed hopper.
[0009] In a further embodiment, the two ends of the folded protective cover are fixed to the edges of the feed hopper and the feed inlet, respectively, and a sliding rod is fixed at each crest of the folded protective cover. The sliding rod is slidably installed in the groove on the inner wall of the feed inlet.
[0010] In a further embodiment, the two ends of the reciprocating lead screw are mounted on the base box via bearing seats, and the length of the reciprocating lead screw is not less than the width of the screen.
[0011] In a further embodiment, a guide rod parallel to the reciprocating lead screw is also installed between the bearing seats, and the guide rod slides through the interior of the slide block.
[0012] In a further embodiment, a cloth cover is installed at the discharge port of the discharge box, and an elastic rope loop is installed around the bottom end of the cloth cover.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This invention features a feed hopper that can reciprocate along the width of the screen. This allows workers to add the masterbatch into the hopper and then move away from the equipment. The reciprocating movement of the feed hopper disperses the masterbatch onto the screen for sieving, saving time and effort. Furthermore, a folding protective cover is installed at the feed inlet to keep the feed inlet covered during the movement of the feed hopper, thereby reducing dust spillage caused by vibration and reducing the risk of workers inhaling dust while operating the equipment.

[0020] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0022] 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.
[0023] Please see Figure 1-4A vibrating screening device for manufacturing decabromodiphenyl ethane masterbatch includes a bottom box 1, a top box 2, a screen 3, a vibrating motor 4, and a discharge box 5. The screen 3 is installed between the bottom box 1 and the top box 2, with the bottom box 1 located below the screen 3 and the top box 2 located above the screen 3. The vibrating motor 4 is installed below the bottom box 1. The discharge boxes 5 are respectively installed at the lower ends of the bottom box 1 and the top box 2, and the two discharge boxes 5 are staggered to facilitate discharge to different locations without interference. An inlet 6 is opened at the higher end of the top box 2, and an inlet hopper 7 is provided inside the inlet hopper 6. Folding protective covers 8 are movably installed between the two sides of the inlet hopper 7 and the edge of the inlet hopper 6. Furthermore, the bottom periphery of the feed hopper 7 is supported by a bracket 9, and a slide 10 is fixed to the edge of the bracket 9. The slide 10 is threaded through and connected to a reciprocating screw 11. A rotary motor 12 is installed at one end of the reciprocating screw 11. When the rotary motor 12 is working, it drives the reciprocating screw 11 to rotate, so that the slide 10 drives the feed hopper 7 to move back and forth along the reciprocating screw 11 through the bracket 9, which facilitates the even spreading of the masterbatch on the surface of the screen 3. At the same time, when the feed hopper 7 moves, it will pull the folded protective cover 8 on one side to extend, while the folded protective cover 8 on the other side will be squeezed and compressed, always keeping the feed inlet 6 covered and reducing dust overflow.
[0024] Specifically, in order to facilitate the temporary storage of masterbatch in the feed hopper 7 when it is added to the feed hopper 7, a partition 71 is slidably installed inside the discharge port of the feed hopper 7. The partition 71 closes the discharge port, and one end of the partition 71 extends out of the outer wall of the feed hopper 7 as a handle, so that the operator can pull the handle to pull out the partition 71 and open the discharge port.
[0025] The two ends of the folding protective cover 8 are fixed to the edges of the feed hopper 7 and the feed inlet 6, respectively. Each crest of the folding protective cover 8 is fixed with a sliding rod 81. The sliding rod 81 is slidably installed in the groove on the inner wall of the feed inlet 6. The groove is parallel to the moving direction of the feed hopper 7, so that the sliding rod 81 always slides in the groove and remains stable, whether the folding protective cover 8 is extended or compressed.
[0026] To improve the stability of the feed hopper 7, the two ends of the reciprocating screw 11 are mounted on the base box 1 via bearing seats 13, and the length of the reciprocating screw 11 is not less than the width of the screen 3, ensuring that the masterbatch is fully dispersed on the screen 3 during feeding. At the same time, a smooth rod 14 parallel to the reciprocating screw 11 is installed between the bearing seats 13, and the smooth rod 14 slides through the interior of the slide block 10, so that the slide block 10 can slide along the smooth rod 14. The smooth rod 14 limits the slide block 10 and prevents it from deflecting on the reciprocating screw 11.
[0027] To further reduce dust, a cloth cover 15 is installed at the discharge port of the discharge box 5, and an elastic rope loop 16 is installed around the bottom end of the cloth cover 15. When the dispersed masterbatch is collected by the receiving cylinder, the elastic rope loop 16 is put around the outside of the receiving cylinder, so that the discharge box 5 and the receiving cylinder are covered by the cloth cover 15, thereby reducing dust overflow.
[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
