Description
Technical Field
[0001] This utility model relates to the field of conveying technology, specifically to a powder feeding hopper and conveying system. Background Technology
[0002] Powdered feeds or feed ingredients play a crucial role in the development of superior new breeds and healthy aquaculture techniques for livestock, poultry, and aquatic products. Firstly, the powdered form directly impacts an animal's digestibility and absorption capacity; suitable particle size can improve the digestibility of nutrients. Secondly, powdered feeds can be mixed with other ingredients during processing, and pelleting improves feed stability and palatability, reducing waste. Furthermore, various feed additives (such as antibiotics, hormones, and health products) are easily added to powdered feeds to optimize their performance and function.
[0003] In the feed production process, powdered feed often requires feeding and conveying. Before entering the feeding pipe, the powder usually needs to enter a feeding hopper and then be fed into the feeding pipe. As the powder passes through the feeding hopper, it is usually filtered to remove impurities, ensure uniformity, and prevent clumping. However, due to its small particle size and poor flowability, powder is prone to clogging during the feeding process, affecting feeding efficiency. Furthermore, the powder tends to stick to the filter, necessitating replacement of the filter to facilitate proper filtration and feeding.
[0004] This utility model provides a novel powder feeding hopper and conveying system to ensure efficient powder filtration during the powder feeding process, avoid clogging, and facilitate easy replacement of the filter structure. It is convenient, flexible, and efficient to use. Utility Model Content

[0025] 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.
[0026] Example 1
[0027] This embodiment provides a powder feeding hopper, such as Figure 1 As shown, it includes an integrally formed feeding section 1, transition section 2, and discharge section 3. The transition section 2 is located between the feeding section 1 and the discharge section 3. The feeding section 1 is a hollow cylindrical shape, the transition section 2 is a hollow inverted frustum shape, and the discharge section 3 is tubular. The discharge section 3 is inclined, and its inclined upper end is connected to the lower end of the transition section 2. A screen plate 4 is detachably installed inside the lower end of the feeding section 1, and a vibrator 5 is installed at the bottom of the screen plate 4. It also includes a drive shaft 6 and two scraper plates 7. A support base 8 is provided below the transition section 2, and a motor 9 is installed inside the support base 8. The lower end of the drive shaft 6 is connected to the motor 9, and its upper end extends through the discharge section 3 to the lower end of the transition section 2. A horizontal connecting rod 10 is provided at the upper end of the drive shaft 6. The two scraper plates 7 are symmetrically placed on the side of the transition section 2, and their lower ends are respectively connected to the two ends of the horizontal connecting rod 10. Their upper ends extend to the part near the screen plate 4 and are detachably connected to the bottom of the screen plate 4. The scraper plates 7 can move on the inner side of the transition section 2.
[0028] In this embodiment, the motor 9 drives the transmission shaft 6 to rotate, which indirectly drives the scraper 7 to rotate and scrape the material, thus avoiding powder blockage during the feeding process of the hopper. In this embodiment, since the scraper 7 and the screen disk 4 are connected, the scraper 7 can rotate and drive the screen disk 4 to rotate, which can filter the powder on the screen disk 4. On this basis, combined with the use of the vibrator 5, the efficiency of powder filtration and feeding is further improved. In this embodiment, the screen disk 4 can be detached from the feeding hopper, which is convenient for replacing or maintaining the screen disk 4, and is flexible and convenient to use.
[0029] Example 2
[0030] In this embodiment, the interior of the screen disk 4 is a filter section 41, such as... Figure 3 As shown, the filter section 41 is symmetrically provided with two connecting rings 42, and the connecting rings 42 and the filter section 41 are evenly connected by several elastic pillars 43; it also includes a guide ring 11, such as Figure 2 and 4 As shown, the guide ring 11 is disposed on the screen plate 4. The vertical cross section of the guide ring 11 is a right-angled triangle. The outer diameter of the guide ring 11 is the same as the inner diameter of the feed part 1. The inner side of the lower surface of the guide ring 11 is fixed to the outer periphery of the filter part 41, and the outer side of the lower surface of the guide ring 11, corresponding to the part of the connecting ring part 42, is placed on the connecting ring part 42.
[0031] The rest is the same as in Example 1.
[0032] In this embodiment, when the screen disk 4 is used, the powder can be guided to the filter section 41 by the guide ring 11. The powder is filtered and discharged by the rotation of the screen disk 4 (the connecting ring 42 rotates by the rotation of the scraper 7) and the vibration of the vibrator 5, so as to prevent the powder from leaking out of the ring with the elastic column 43 and failing to pass through the filter.
[0033] Example 3
[0034] In this embodiment, the screen disc 4 is detachably located at the lower end of the feed section 1, as shown in the following structure. Figure 2 As shown, an annular groove 12 is provided outward at the lower end of the feed section 1. The elasticity of the elastic column 43 causes the end of the connecting ring 42 of the screen disk 4 to be placed inside the annular groove 12. The connecting ring 42 can rotate within the annular groove 12. The part where the top of the annular groove 12 connects to the side of the feed section 1 is a curved surface, and the part where the top surface and the side of the connecting ring 42 connect is also a curved surface. Figure 2 As shown.
[0035] The rest is the same as in Example 2.
[0036] In this embodiment, during installation, the screen disc 4 can be moved downwards in the feed section 1 by pressing the two connecting rings 42 inwards against the elastic column 43. When the connecting rings 42 move to the position of the annular groove 12, the connecting rings 42 are no longer squeezed by the side of the feed section 1 and are rebounded into the annular groove 12 by the elastic force of the elastic column 43 to complete the installation. When it is necessary to remove the screen disc 4 for replacement or maintenance, the screen disc 4 can be moved upwards. Since the top and side surfaces of the connecting rings 42 are curved, and the top of the annular groove 12 and the side surface of the feed section 1 are also curved, the upward movement of the screen disc 4 can reduce the resistance when the curved surfaces come into contact, and then press the elastic column 43 out of the annular groove 12, thereby removing the screen disc 4 upwards. This makes it flexible and convenient to use.
[0037] Example 4
[0038] In this embodiment, the ratio of the width of the connecting ring 42 to the radius of the filter 41 is 1:8; the ratio of the width of the ring formed by the plurality of elastic pillars 43 to the width of the connecting ring 42 is 2:3. The width of the ring formed by the elastic pillars 43 is the distance between the connecting ring 42 and the filter 41 when the elastic pillars 43 are not subjected to external force.
[0039] The rest is the same as in Example 2.
[0040] The above ratio ensures that the area of the filter section 41 is as large as possible while maintaining stable installation, thus guaranteeing the filtration efficiency of the powder.
[0041] Example 5
[0042] In this embodiment, the scraper plate 7 and the screen plate 4 are detachably connected at the bottom as follows: a fixed post 13 extends vertically upward from the upper end of the scraper plate 7, and a slot 15 is provided inside the fixed post 13. The lower surfaces of the two connecting rings 42 are respectively provided with insert rods 16 corresponding to the two slots 15, and the insert rods 16 are inserted into the slots 15.
[0043] The rest is the same as in Example 3.
[0044] In this embodiment, when the screen plate 4 is installed, the insertion rod 16 gradually moves down as the screen plate 4 moves down. When the connecting ring 42 is engaged in the ring groove 12, the insertion rod 16 is inserted into the slot 15. When the scraper plate 7 rotates, it can drive the insertion rod 16 to rotate, thereby driving the screen plate 4 to rotate for screening and feeding.
[0045] Example 6
[0046] In this embodiment, the number of vibrators 5 is four, such as... Figure 3 As shown, the four vibrators 5 are all located on the bottom surface of the filter section 41 and are evenly distributed around the periphery of the filter section 41.
[0047] The rest is the same as in Example 1.
[0048] The vibration of vibrator 5 improves the efficiency of powder feeding. The uniform distribution of vibrator 5 ensures the uniformity of powder feeding.
[0049] Example 7
[0050] In this embodiment, the inclination angle of the discharge section 3 is 60-70°, and the drive shaft 6 is provided with agitator blades 17 evenly along its circumference at the connection between the discharge section 3 and the transition section 2. Figure 1 As shown.
[0051] The rest is the same as in Example 1.
[0052] The agitator 17 is designed to agitate the material at the connection between the discharge section 3 and the transition section 2 while the drive shaft 6 is rotating, thus preventing blockage and ensuring efficient material discharge.
[0053] Example 8
[0054] This embodiment further provides a powder conveying system based on any of the above embodiments, such as... Figure 5 As shown, it includes a powder feeding hopper, a feeding pipe 18, and a blower 19. The feeding pipe 18 is connected to the lower end of the discharge section 3. The blower 19 is located on the feeding pipe 18, and its position on the feeding pipe 18 is located behind the conveying part of the discharge section 3. The air inlet end of the blower 19 is provided with a filter screen 20.
[0055] In this embodiment, the powder conveying system, during use, uses a blower 19 to supply air into the feeding pipe 18, and simultaneously uses the air supply to convey the material exiting the discharge section 3. The conveying direction is the same as the air supply and material feeding direction of the blower 19. Figure 5 The direction of the arrow in the diagram indicates the air supply direction and the material feeding direction. The opposite direction is the conveying direction. The powder is conveyed to the next equipment for storage or use by the blower 19.
[0056] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the concept and scope of the present utility model. Without departing from the design concept of the present utility model, all modifications and improvements made by those skilled in the art to the technical solutions of the present utility model should fall within the protection scope of the present utility model. The technical content for which protection is sought in the present utility model has been fully recorded in the technical requirements.
