Description

Technical Field

[0001] This utility model relates to the field of material feeder technology, and more specifically, to a material feeder that prevents material blockage. Background Technology

[0002] Thermal power generation utilizes the combustion of fossil fuels to produce heat energy, primarily coal, converting thermal energy into mechanical energy, which is then converted into electrical energy by a generator. In the daily operation of power plants, material distributors are widely used in multiple stages, playing a crucial role, especially in the screening and feeding of coal. The material distributor evenly distributes the crushed coal material.

[0003] Existing patent CN212441992U discloses a constant uniform feeder for a coal crusher in a coal conveying system of a thermal power plant, including a base plate. A first electric push rod is fixedly connected to one side of the base plate, and a first bearing is fixedly connected to one side of the first electric push rod. The advantage of this invention is that, during use, the feed inlet of the coal crusher is positioned above the screen plate near the first electric push rod. Under the action of gravity, the coal moves from a higher position to a lower position on the screen plate. During this movement, the screen plate ensures that the volume of coal remains relatively uniform during distribution, facilitating even distribution.

[0004] However, this existing feeder still has shortcomings. In this feeder, a certain amount of coal is sealed in the feed pipe and then discharged after the opening and closing of two baffles installed in the feed pipe. However, in actual operation, the opening and closing process of the two baffles is greatly hindered, and the coal is easy to get stuck in the baffles. In addition, when the coal contains a high proportion of fine powder or has too high moisture content, some of the coal will become viscous, affecting its flowability. Some of the viscous coal will adhere to the wall of the feed pipe, causing blockage of the feed pipe after a period of time, which will greatly affect the coal discharge effect.

[0005] Therefore, it is necessary to provide a material distributor that prevents material blockage and solves the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to provide a material feeder that prevents material blockage in order to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A material distributor for preventing material blockage includes a receiving hopper and a screen plate disposed thereon, wherein a discharge pipe is connected to the bottom of the receiving hopper, and further includes:

[0009] A fabric box is installed on the feed pipe, and both the upper and lower ends of the fabric box are connected to the feed pipe;

[0010] A connecting column is rotatably mounted on the inner wall of the fabric box. The connecting column is provided with multiple material stop seats, and a fabric cavity is provided between adjacent material stop seats.

[0011] Four scrapers are slidably disposed on the inner walls of the feed pipe.

[0012] A transmission mechanism is provided in the fabric box to drive the connecting column to rotate and simultaneously drive the scraper to move up and down along the inner wall of the feed pipe.

[0013] Furthermore, each of the scrapers has an upright plate at its upper end, and the ends of the four upright plates are connected to a top frame.

[0014] Furthermore, the transmission mechanism includes:

[0015] A rotating shaft is rotatably mounted on the front and rear walls of the fabric box. The connecting column is connected to the rotating shaft, and a driving component connected to the rotating shaft is provided on the outer wall of the fabric box.

[0016] A crankshaft is rotatably mounted on the front and rear walls of the receiving hopper. A sleeve is movably fitted at the bend of the crankshaft, and a connecting rod is hinged to the sleeve. The lower end of the connecting rod is hinged to the top frame.

[0017] The linkage component cooperates with the rotating shaft and drives the crankshaft to rotate.

[0018] Furthermore, the linkage component includes a rotating rod rotatably mounted on the outer wall of the receiving hopper, a first gear mounted on the rotating rod, a second gear meshing with the first gear mounted on the crankshaft, and a belt connecting the crankshaft and the rotating rod via a pulley drive.

[0019] Furthermore, a plug rod is provided at the bottom of the top frame, and a protective seat is provided at the upper end of the top frame that is hinged to the connecting rod. A motor connected to the plug rod is provided inside the protective seat.

[0020] Furthermore, the inner wall of the feeding pipe is provided with a sliding groove, and a slider connected to the scraper is slidably disposed on the inner wall of the sliding groove.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This design uses a transmission mechanism to drive the connecting column and the baffle seat to rotate. When one of the feeding chambers rotates to the top, the coal in the discharge pipe enters that chamber. When the feeding chamber is full and rotates to the bottom, the coal can be discharged, thus completing the coal feeding operation. The amount of coal in the feeding chamber is fixed, ensuring that the amount discharged each time is uniform and consistent. This achieves constant and quantitative coal feeding, improving the subsequent processing of the discharged coal. Furthermore, the method of rotating the feeding chamber via the connecting column reduces obstruction and jamming, resulting in more stable and accurate coal feeding. This also significantly extends the service life and performance of the feeder, making it highly practical.

[0023] When the transmission mechanism is operating, it will also drive the scraper to move up and down along the inner wall of the feed pipe. The scraper can remove the coal material adhering to the inner wall of the feed pipe, which can prevent some viscous material from adhering to the inner wall of the feed pipe, thereby effectively preventing the feed pipe from getting blocked, improving the fluidity of the coal material, and thus improving the feeding performance.

[0032] 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.

[0033] Please see Figure 1-6 A material distributor for preventing material blockage includes a receiving hopper 1 and a screen plate 2 disposed thereon, the bottom of the receiving hopper 1 is connected to a discharge pipe 3, and further includes:

[0034] Fabric box 4 is installed on feed pipe 3, and both the upper and lower ends of fabric box 4 are connected to feed pipe 3;

[0035] The connecting column 5 is rotatably mounted on the inner wall of the material box 4. Multiple material stop seats 6 are provided on the connecting column 5, and a material feeding cavity 7 is provided between adjacent material stop seats 6.

[0036] Four scrapers 8 are slidably disposed on the inner walls of the feed pipe 3.

[0037] The transmission mechanism 9 is located in the fabric box 4 and is used to drive the connecting column 5 to rotate, and simultaneously drive the scraper 8 to move up and down along the inner wall of the feed pipe 3.

[0038] During use, the crushed coal feed inlet is located high above the screen plate 2. The coal will fall onto the screen plate 2 first, and the coal will be screened by the screen plate 2. The larger coal that does not meet the standard will move along the screen plate 2, and finally be removed from the screen plate 2 and conveyed away for further crushing. Small-volume coal pieces meeting the standards on screen plate 2 pass through screen plate 2 and fall into receiving hopper 1. The coal in receiving hopper 1 then enters the discharge pipe 3. Simultaneously, the transmission mechanism 9 drives the connecting column 5 to rotate, which in turn drives the baffle seat 6 to rotate. When one of the feeding chambers 7 rotates to the top, i.e., is in the position of the upper discharge pipe 3, the coal in the discharge pipe 3 will enter this feeding chamber 7. The transmission mechanism 9 will continue to drive the connecting column 5 and the baffle seat 6 to move, and the feeding chamber 7 that has received the coal will also rotate with the connecting column 5. The feeding chamber 7 that is full of coal will rotate to another position. When the next feeding chamber 7 is in the position of the upper discharge pipe 3, it will continue to feed, and so on. When the feeding chamber 7 that is full of coal rotates to the bottom position, the feeding chamber 7 is aligned with the lower discharge pipe 3, and the coal in the feeding chamber 7 will be discharged from the bottom discharge pipe 3. Figure 3As shown in the diagram, the example rotation is clockwise, which completes the coal feeding operation. The coal in the feeding chamber 7 is quantitative, ensuring that the amount of coal discharged through the chamber is uniform and consistent each time. The feeding chamber 7 achieves constant and quantitative coal feeding, improving subsequent processing of the fed coal. Furthermore, the rotation of the feeding chamber 7 via the connecting column 5 reduces obstruction and jamming, resulting in more stable and accurate coal feeding. This significantly extends the lifespan and performance of the feeder, making it highly practical.

[0039] When the transmission mechanism 9 operates, it will also drive the scraper 8 to move up and down along the inner wall of the feed pipe 3. That is, the scraper 8 can scrape off the coal material adhering to the inner wall of the feed pipe 3, which can prevent some viscous material from adhering to the inner wall of the feed pipe 3, thereby effectively preventing the feed pipe 3 from becoming blocked, improving the fluidity of the coal material, and further improving the feeding performance.

[0040] For preferred options, please refer to [link / reference]. Figure 3-6 Each scraper 8 has a vertical plate 10 at its upper end, and the ends of the four vertical plates 10 are connected to a top frame 11. With this design, the scraper 8 can be moved up and down along the inner wall of the feed pipe 3 by the up and down movement of the top frame 11 and the vertical plates 10, which facilitates connection with the scraper 8 and drives its movement.

[0041] For preferred options, please refer to [link / reference]. Figure 1-3 and Figure 5-6 The transmission mechanism 9 includes:

[0042] A rotating shaft 91 is rotatably mounted on the front and rear walls of the fabric box 4. A connecting column 5 is connected to the rotating shaft 91. A driving component 92 connected to the rotating shaft 91 is provided on the outer wall of the fabric box 4. The driving component 92 in this application can be a servo motor.

[0043] A crankshaft 93 is rotatably mounted on the front and rear walls of the receiving hopper 1. A sleeve 94 is movably fitted at the bend of the crankshaft 93. A connecting rod 95 is hinged to the sleeve 94. The lower end of the connecting rod 95 is hinged to the top frame 11.

[0044] The linkage component 96 works in conjunction with the rotating shaft 91 to drive the crankshaft 93 to rotate.

[0045] Specifically, starting the drive unit 92 can drive the rotating shaft 91 to rotate, which in turn drives the connecting column 5 and the baffle seat 6 to rotate, thus causing the material feeding chamber 7 to rotate to different positions. Simultaneously, when the rotating shaft 91 rotates, it also synchronously drives the crankshaft 93 to rotate via the linkage component 96. The crankshaft 93 drives the sleeve 94 to rotate, which, in conjunction with the connecting rod 95, causes the top frame 11 to move up and down reciprocally. This, in turn, causes the scraper 8 to move up and down reciprocally along the inner wall of the discharge pipe 3, achieving the effect of scraping and cleaning the inner wall of the discharge pipe 3. The linkage component 96 enables this linkage effect, improving the synchronization of the device, reducing the failure rate and energy consumption, and lowering procurement and operating costs.

[0046] For preferred options, please refer to [link / reference]. Figure 1 -and Figure 5 The linkage component 96 includes a rotating rod 961 rotatably mounted on the outer wall of the receiving hopper 1, a first gear 962 mounted on the rotating rod 961, a second gear 963 meshing with the first gear 962 mounted on the crankshaft 93, and a belt 964 connecting the crankshaft 93 and the rotating shaft 91 via a pulley drive.

[0047] With this design, when the drive component 92 drives the rotating shaft 91 to rotate, the rotating shaft 91 will drive the rotating rod 961 and the first gear 962 to rotate via the belt 964. The first gear 962 will then drive the second gear 963 and the crankshaft 93 to rotate, thus achieving a linkage effect. Furthermore, the first gear 962 is a large gear, and the second gear 963 is a small gear, meaning that when the first gear 962 rotates once, it drives the second gear 963 to rotate many times.

[0048] by Figure 2-3 Taking the display status as an example, the transmission ratio of the first gear 962 and the second gear 963 is 1:4, that is, when the first gear 962 rotates one revolution, the second gear 963 rotates four revolutions. Figure 3 Each time the four feeding chambers 7 rotate to the top to receive material, only the rotating shaft 91 and the connecting column 5 need to rotate 1 / 4 turn. At this time, the linkage component 96 causes the crankshaft 93 to rotate one turn, thereby causing the scraper 8 to move down and up once. This cycle continues. That is, when the feeding chamber 7 is at the top, the scraper 8 tends to move downward, and when the baffle seat 6 is at the top, the scraper 8 tends to move upward. This makes it easier for the scraper 8 to scrape the coal and move it into the feeding chamber 7, resulting in good performance.

[0049] For preferred options, please refer to [link / reference]. Figure 6A blocking rod 12 is installed at the bottom of the top frame 11, and a protective seat 13 hinged to the connecting rod 95 is installed at the upper end of the top frame 11. A motor connected to the blocking rod 12 is installed inside the protective seat 13. This design ensures that when the top frame 11 moves downward, it will cause the blocking rod 12 to move downward, further preventing coal blockage in the feed pipe 3. Furthermore, the motor in the protective seat 13 can rotate the blocking rod 12, agitating the coal in the feed pipe 3, reducing blockage and improving feed efficiency.

[0050] For preferred options, please refer to [link / reference]. Figure 3-6 The inner wall of the feeding pipe 3 is provided with a groove 14, and a slider 15 connected to the scraper 8 is slidably disposed on the inner wall of the groove 14. With this design, when the scraper 8 moves, it will drive the slider 15 to slide along the groove 14, thereby improving the movement stability of the scraper 8 and thus improving the scraping effect.
