Technical Field
[0001] This utility model relates to the field of gypsum powder production technology, and in particular to a splash-proof pulverizing device for gypsum powder production. Background Technology
[0002] Gypsum powder is an important industrial raw material and building material, widely used in construction, agriculture, medicine, chemical industry and many other fields. In the production process of gypsum powder, crushing equipment is usually used to crush large pieces of gypsum raw materials into powder of the desired particle size.
[0003] According to the search, the Chinese patent "A Phosphogypsum Powder Production and Crushing Equipment" authorized announcement number "CN220091549U" uses two staggered dust baffles in the placement frame to suppress dust on the crushed gypsum inside the machine casing, thus ensuring a good working environment.
[0004] The aforementioned application states that the gypsum blocks generate a large amount of dust during crushing, which can easily cause the dust inside the machine casing to splash out through the space of two staggered dust baffles, thereby affecting the working environment.
[0005] Therefore, a splash-proof pulverizing device for gypsum powder production is proposed to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a splash-proof pulverizing device for gypsum powder production in order to solve the above-mentioned problems, thereby improving the problem of dust splashing out of the machine casing through the space of two phase-displaced dust baffles.
[0007] This utility model achieves the above-mentioned objective through the following technical solution: a pulverizing device for gypsum powder production with anti-splashing capability, comprising: a pulverizer, with a feed hopper fixedly connected to the top of the pulverizer; and an anti-splashing mechanism, the anti-splashing mechanism including baffles hinged to both sides of the inner wall of the feed hopper, with coil springs fixedly connected to the surface of the baffles, two mounting frames fixedly connected to the front end of the feed hopper, the other end of the coil springs fixedly connected to the inner wall of the mounting frames, and guide plates and limiting plates fixedly connected to both sides of the inner wall of the feed hopper, the tops of the guide plates and limiting plates forming an angle with the horizontal plane. Through the baffles and coil springs, when there is no material in the feed hopper, the elastic force of the coil springs pushes the baffles to flip, thereby sealing the feed hopper with the two baffles. The two downward-sloping limiting plates prevent a large amount of gypsum material from splashing to the bottom of the baffles, ensuring that the two baffles stably seal the feed hopper, thus preventing dust from splashing out of the feed hopper and ensuring a safe working environment.
[0008] Preferably, the inner wall of the feed hopper is rotatably connected to a striking frame, and the surface of the striking frame is fixedly connected with equally arranged conical rods.
[0009] Preferably, an irregular gear is fixedly connected to one end of the striking frame, an electric push rod is fixedly connected to the front end of the feed hopper, a rack ring is fixedly connected to the telescopic end of the electric push rod, and the surface of the irregular gear is meshed with the inner surface of the rack ring. Through the electric push rod, rack ring, and irregular gear, the striking frame and cone rod reciprocate within the feed hopper, causing the striking frame to strike the two limiting plates during this reciprocating motion, thus rapidly dropping the gypsum material into the crusher.
[0010] Preferably, a movable disc is fixedly connected to the front end of the baffle.
[0011] Preferably, a spring is fixedly connected to the front end of the feed hopper, and a slide is fixedly connected to the other end of the spring. The surface of the slide is slidably connected to the inner wall of the mounting frame.
[0012] Preferably, a limiting block is fixedly connected to the surface of the mounting frame. The limiting block restricts the rotation direction of the movable disc, thereby ensuring the carriage is precisely engaged within the movable disc.
[0013] Preferably, a limiting frame is fixedly connected to the front end of the feed hopper, and the upper end of the inner wall of the rack ring is slidably connected to the surface of the limiting frame. The limiting frame effectively limits the movement of the rack ring, ensuring its stability during movement.
[0014] The beneficial effects of this utility model are:
[0015] By using baffles and coil springs, the elastic force of the coil springs pushes the baffles to flip after the feed hopper is empty, thereby sealing the feed hopper with two baffles. The two downward-sloping limiting plates prevent a large amount of gypsum material from splashing to the bottom of the baffles, ensuring that the two baffles stably seal the feed hopper. Compared with the dust in existing powder and water equipment, which is easy to splash out, this method prevents dust from splashing out of the feed hopper by sealing the feed hopper, thus ensuring the working environment.
[0016] The electric push rod, rack and pinion ring and irregular gear realize the reciprocating swing of the striking frame and cone rod in the feed hopper, so that the striking frame strikes the two limiting plates in the reciprocating swing, so that the gypsum material falls into the crusher quickly.

[0023] 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.
[0024] In practical implementation: such as Figure 1-5 As shown, a splash-proof pulverizing device for gypsum powder production includes: a pulverizer 1, with a feed hopper 2 fixedly connected to the top of the pulverizer 1; and a splash-proof mechanism 3, which includes baffles 31 hinged to both sides of the inner wall of the feed hopper 2, with coil springs 33 fixedly connected to the surface of the baffles 31, two mounting frames 32 fixedly connected to the front end of the feed hopper 2, the other end of the coil springs 33 fixedly connected to the inner wall of the mounting frames 32, and guide plates 35 and limiting plates 36 fixedly connected to both sides of the inner wall of the feed hopper 2, with the tops of the guide plates 35 and the limiting plates 36 forming an angle with the horizontal plane.
[0025] Two crushing rollers are rotatably connected to the inner wall of the crusher 1. A gear is fixedly connected to one end of each roller, and the two gears mesh. A first servo motor is fixedly connected to the front end of the crusher 1, and the output shaft of the first servo motor is fixedly connected to one end of one of the gears. A dust sealing plate is hinged to the lower end of the inner wall of the crusher 1. A second servo motor is fixedly connected to the lower end of the surface of the crusher 1, and the output shaft of the second servo motor is fixedly connected to the front end of the dust sealing plate. The upper surface of the feed hopper 2 is inclined.
[0026] When gypsum material needs to be crushed, the gypsum material is poured into the feed hopper 2, and the gypsum material in the feed hopper 2 is guided to the baffle 31 by the guide plate 35. The excessive weight of the gypsum material causes the baffle 31 to flip and move downward, opening the interior of the feed hopper 2 and allowing the gypsum material to fall into the crusher 1. After a certain amount of gypsum material has been poured in, the positioning of the baffle 31 is released, and the elastic force of the coil spring 33 pushes the baffle 31 to flip and move upward, thus sealing the feed hopper 2 with the two baffles 31. At this time, the first servo motor is manually turned on. The output shaft of the first servo motor rotates, driving one of the gears to rotate, and the rotation of one gear drives the rotation of the other gear, causing the two powder rollers to crush the gypsum material. The gypsum dust splashed in the crusher 1 splashes towards the feed hopper 2. Because the two limiting plates 36 are tilted downward, a large amount of dust is blocked from splashing to the bottom of the baffle 31.
[0027] After crushing is complete, manually turn off the first servo motor and turn on the second servo motor, which will cause the dust cover plate to flip, opening the lower end of the inner wall of the crusher 1 and allowing the crushed gypsum powder inside the crusher 1 to be discharged.
[0028] like Figure 5 As shown, a striking frame 37 is rotatably connected to the inner wall of the feed hopper 2. Conical rods 38 arranged in equal rows are fixedly connected to the surface of the striking frame 37. An irregular gear 39 is fixedly connected to one end of the striking frame 37. An electric push rod 311 is fixedly connected to the front end of the feed hopper 2. A rack ring 310 is fixedly connected to the telescopic end of the electric push rod 311. The surface of the irregular gear 39 is meshed with the inner surface of the rack ring 310. A limit frame 312 is fixedly connected to the front end of the feed hopper 2. The upper end of the inner wall of the rack ring 310 is slidably connected to the surface of the limit frame 312.
[0029] When the electric push rod 311 is manually activated, the telescopic end of the electric push rod 311 moves, pushing the rack ring 310 to move. As the rack ring 310 moves, it drives the irregular gear 39 to rotate. One side of the rack ring 310 moves and abuts against one side of the limit frame 312. At this time, the telescopic end of the electric push rod 311 will drive the rack ring 310 to move in the opposite direction, thereby causing the irregular gear 39 to rotate back and forth and drive the striking frame 37 and the cone rod 38 to swing back and forth, so that the striking frame 37 strikes the limiting plate 36, causing the material on the limiting plate 36 to fall quickly into the crusher 1.
[0030] like Figure 4 As shown, a movable disc 34 is fixedly connected to the front end of the baffle 31, a spring 314 is fixedly connected to the front end of the feed hopper 2, a slide 313 is fixedly connected to the other end of the spring 314, the surface of the slide 313 is slidably connected to the inner wall of the mounting frame 32, and a limit block 315 is fixedly connected to the surface of the mounting frame 32.
[0031] In use, gypsum material is poured into the feed hopper 2, and the gypsum material in the feed hopper 2 is guided to the baffle 31 by the guide plate 35. The excessive weight of the gypsum material causes the baffle 31 to flip and move downwards, or the operator pushes the movable plate 34 to make the baffle 31 flip and stick to the inner wall of the feed hopper 2. At this time, the elastic force of the spring 314 pushes the slide 313 to move and engage with the movable plate 34, making the interior of the feed hopper 2 stable and open, allowing the gypsum material to fall into the crusher 1. After a certain amount of gypsum material has been poured in, the slide 313 is pushed away from the movable plate 34, releasing the positioning of the baffle 31. The elastic force of the coil spring 33 pushes the baffle 31 to flip and move upwards, thereby sealing the inside of the feed hopper 2 with the two baffles 31.
[0032] It should be noted that the crusher 1, the first servo motor, the second servo motor, the crushing roller, the feed hopper 2, the dust sealing plate, the electric push rod 311, the irregular gear 39, the rack ring 310, the coil spring 33, and the spring 314 mentioned above are all components with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the first servo motor, the second servo motor, and the electric push rod 311 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.
[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
