Description

Technical Field

[0001] This application relates to the field of flour conveying, and in particular to a flour conveying device. Background Technology

[0002] Flour is a staple food that people often consume. It is rich in protein, generally containing 10%-13%, which is higher than that of rice. The bread baking process involves making cakes, cookies, pastries, and puff pastries from flour.

[0003] The bread baking process begins with mixing flour and water, adding yeast and other ingredients, and kneading into a smooth dough. On a bread baking production line, a flour conveying device is typically used to transport the flour. This device includes a hopper, with a control valve at the bottom to regulate the discharge. When the valve is open, the flour in the hopper enters a negative pressure pipe from the bottom, and then proceeds through the negative pressure pipe into subsequent production stages.

[0004] Regarding the aforementioned technologies, flour in the storage hopper tends to clump together on the inner wall of the hopper, resulting in insufficient feeding. If the flour on the inner wall of the storage hopper is not cleaned in time, more and more flour will adhere to the inner wall of the storage hopper, which may also cause blockage of the outlet of the storage hopper. Utility Model Content

[0005] To facilitate the cleaning of flour from the inner wall of the storage hopper, this application provides a flour conveying device.

[0006] The flour conveying device provided in this application adopts the following technical solution:

[0007] A flour conveying device includes a storage hopper. The storage hopper is equipped with a cleaning assembly, which includes multiple sets of nozzles distributed on the inner wall of the storage hopper. Each set of nozzles is connected to a spray pipe, and the multiple sets of nozzles are connected to a gas generating assembly through the spray pipe. Each set of nozzles includes multiple spray bars connected to the spray pipe in a scattering pattern. Each spray bar has a nozzle, which is inclined towards the inner wall of the storage hopper.

[0008] By adopting the above technical solution, the storage hopper is equipped with multiple sets of nozzles, which, driven by the gas generating component, achieve efficient and automatic cleaning of the inner wall of the storage hopper. The design of the nozzles and spray nozzles improves the cleaning effect of the inner wall of the storage hopper, reduces the possibility of flour accumulation and clumping, thereby maintaining the cleanliness of the storage hopper and the flowability of the material.

[0009] Optionally, the nozzle includes a fixed part and multiple movable parts. The fixed part is fixedly connected to the storage hopper, and the multiple movable parts correspond one-to-one with multiple sets of nozzles. One end of each movable part is fixedly connected to the corresponding multiple nozzles. The end of the movable part away from the nozzle is rotatably connected to the end of the fixed part. The opening direction of the multiple nozzles in each set of nozzles is opposite to the rotation direction of the movable part.

[0010] By adopting the above technical solutions, the multi-spray bar design and rotating mechanism of the nozzles expand the cleaning range, thereby reducing the number of nozzles and effectively lowering manufacturing and maintenance costs. The flexible rotation of the nozzles not only improves cleaning efficiency but also makes the cleaning process more uniform.

[0011] Optionally, the nozzles of the multiple nozzles within each group of nozzles are located at different positions relative to the nozzle openings.

[0012] By adopting the above technical solution, the nozzles of the spray pipes in each group of nozzles are opened at different positions, so that the nozzles can clean the inner wall of the storage hopper from multiple positions. This design greatly improves the cleaning coverage.

[0013] Optionally, each of the movable parts is provided with a sleeve at a position corresponding to the fixed part, the sleeve being slidably connected to the movable part and rotatably connected to the fixed part.

[0014] By adopting the above technical solution, the sliding connection design between the moving part and the sleeve allows the moving part to rotate and slide flexibly under the support of the fixed part. The sliding of the moving part increases the cleaning range of the nozzle and further improves the cleaning effect. The rotating connection of the sleeve ensures the smoothness of the moving part during rotation.

[0015] Optionally, a sliding groove is provided inside the sleeve, and a sliding block is fixedly connected to the movable part, and the sliding block slides in the sliding groove.

[0016] By adopting the above technical solution, the cooperative design of the sliding groove and the sliding block provides a stable sliding path for the moving part, thereby improving the stability of the sliding process of the moving part.

[0017] Optionally, neither end of the sliding groove is connected to either end of the sleeve.

[0018] By adopting the above technical solution, the two ends of the sliding groove are not connected to the end of the sleeve, which limits the sliding distance of the moving part and prevents equipment damage or instability that may be caused by excessive movement. By precisely controlling the sliding distance, the sliding groove ensures the stability of the moving part during rotation and sliding.

[0019] Optionally, the sleeve is provided with a bearing, and the sleeve is rotatably connected to the fixed part through the bearing.

[0020] By adopting the above technical solution, the bearing installed inside the sleeve provides low-friction and high-efficiency support for the rotation of the moving part. The use of bearings reduces energy consumption during rotation and improves the reliability and stability of the moving part during long-term operation.

[0021] Optionally, each of the nozzles is provided with a flexible constriction nozzle, which can open under the action of gas in the spray bar and retract when there is no gas output.

[0022] By adopting the above technical solution, the flexible contraction nozzle equipped with the nozzle can automatically open when there is gas output and automatically contract when there is no gas output. This intelligent design effectively prevents flour from entering the nozzle when not in operation, reducing the risk of nozzle blockage.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The storage hopper is equipped with multiple sets of nozzles, which, driven by the gas generating component, achieve efficient automatic cleaning of the inner wall of the storage hopper. The design of the nozzles and spray nozzles improves the cleaning effect of the inner wall of the storage hopper, reduces the possibility of flour accumulation and clumping, thereby maintaining the cleanliness of the storage hopper and the flowability of the material;

[0025] 2. By setting up an movable part, the cleaning area of ​​the nozzle can be expanded, further reducing the clumping of flour on the inner wall of the storage hopper, while also reducing the number of nozzle sets used and saving costs;

[0026] 3. A constriction nozzle is installed at the nozzle to prevent flour from entering the nozzle pipe and causing blockage, thus ensuring the stability of the nozzle's airflow. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

In the description of this specification, references to terms such as "an embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0034] This application discloses a flour conveying device. (Refer to...) Figure 1 A flour conveying device includes a storage hopper 1, with a feed inlet at the top and a discharge valve at the bottom. A cleaning assembly 2 is installed on the inner wall of the storage hopper 1, comprising multiple sets of nozzles 3 distributed along the inner wall of the storage hopper 1. Each set of nozzles 3 is connected to a spray pipe 4, and the multiple sets of nozzles 3 are connected to a gas generating assembly 5 via the spray pipes 4.

[0035] Specifically, refer to Figure 2 and Figure 3 Each nozzle group 3 includes multiple spray bars 31, which are connected to the spray pipe 4 in a scattering pattern, meaning the spray bars 31 are tilted in different directions. Each spray bar 31 has a nozzle 32, which is tilted so that it faces the inner wall of the storage hopper 1. When flour adheres to the inner wall of the storage hopper 1, the gas generating component 5 is activated. The high-pressure gas generated by the gas generating component 5 enters the nozzle 3 through the spray pipe 4 and is finally ejected from the nozzle 32. Because the nozzle 32 is tilted, the high-pressure gas is sprayed towards the inner wall of the storage hopper 1, thereby breaking up and blowing off the flour adhering to the inner wall of the storage hopper 1, thus achieving the cleaning function of the storage hopper 1.

[0036] In this embodiment, refer to Figure 3 The nozzle 4 includes a fixed part 41 and multiple movable parts 42. The fixed part 41 is fixedly connected to the outer wall of the storage hopper 1, and the multiple movable parts 42 are arranged one-to-one with multiple sets of nozzles 3. One end of each movable part 42 is fixedly connected to the corresponding multiple spray bars 31, and the other end is rotatably connected to the fixed part 41.

[0037] Reference Figure 3 In each group of nozzles 3, the multiple nozzles 32 are oriented in the opposite direction to the rotation direction of the movable part 42. When high-pressure gas is ejected from the nozzles 32, the high-pressure gas provides a pushing force to the spray rod 31, causing the movable part 42 to rotate. The rotation of the movable part 42 and the spray rod 31 changes the spray position of the nozzles 32, expanding the cleaning range. To further improve the flexibility of the nozzles 3, a sleeve 6 is provided at the position of each movable part 42 corresponding to the fixed part 41. The sleeve 6 is slidably connected to the movable part 42 and rotatably connected to the fixed part 41. To reduce the rotational friction between the sleeve 6 and the fixed part 41 and improve the smoothness of rotation, a bearing 61 is installed between the sleeve 6 and the fixed part 41. Through the support and lubrication of the bearing 61, the sleeve 6 can rotate more smoothly on the fixed part 41.

[0038] Specifically, refer to Figure 3 A sliding groove 62 along the length of the sleeve 6 is formed inside the sleeve 6. A sliding block 421 is fixedly connected to the outer wall of the movable part 42, and the sliding block 421 can slide within the sliding groove 62. This arrangement allows the movable part 42 to not only rotate on the fixed part 41, but also slide on the fixed part 41, thereby further improving the flexibility of the nozzle 3 and expanding the cleaning range. To prevent the sliding block 421 from sliding out of the sliding groove 62, both ends of the sliding groove 62 are closed, and neither end of the sliding groove 62 is connected to either end of the sleeve 6.

[0039] Reference Figure 3 A spring 422 is rotatably connected to one end of the movable part 42 located inside the sleeve 6. One end of the spring 422 is connected to the movable part 42, and the other end is connected to the sleeve 6. When the high-pressure gas in the nozzle 4 is ejected from the nozzle 32, the high-pressure gas will push the movable part 42 to move away from the fixed part 41 against the elastic force of the spring 422, realizing the movement of the movable part 42 relative to the fixed part 41 along the axial direction. During the extension of the movable part 42, the spray range of the nozzle 4 will be expanded, realizing the dispersal of the flour on the inner wall of the storage hopper 1. When the gas generating component 5 stops outputting high-pressure gas, the spring 422 drives the movable part 42 to move closer to the fixed part 41, so that the movable part 42 returns to its original position.

[0040] Furthermore, refer to Figure 3The nozzles 32 on the multiple spray bars 31 within each group of nozzles 3 are positioned differently. This arrangement allows each nozzle 32 to spray and clean the inner wall of the storage hopper 1 from different positions, thereby improving the cleaning effect and efficiency.

[0041] In addition, refer to Figure 3 Each nozzle 32 is equipped with a flexible constriction nozzle 33. The constriction nozzle 33 can open under the action of gas in the spray bar 31, and is in a constricted state when there is no gas output. This design prevents flour from entering the nozzle 3 when not in use, thus preventing clogging. It ensures that the nozzle 3 remains unobstructed during each use, improving cleaning effectiveness and stability.

[0042] The nozzle 4 is made of wear-resistant and corrosion-resistant materials, such as plastic or stainless steel alloy. This extends the service life of the nozzle 4 and reduces performance degradation caused by wear or corrosion. Furthermore, for ease of maintenance and replacement, the constriction nozzle 33 is designed to be detachable. When a constriction nozzle 33 becomes clogged and requires cleaning, the operator can remove it from the nozzle for repair or replacement. This modular design not only improves maintenance efficiency but also reduces overall operating costs.

[0043] The gas generating assembly 5 includes an air compressor for generating high-pressure gas so that it can quickly and stably supply gas to the nozzle 3 when needed.

[0044] The implementation principle of this embodiment is as follows: This application provides a highly efficient, flexible, and safe flour conveying device cleaning component 2 through a series of innovative designs and optimization measures. The nozzle 4 includes a fixed part 41 and a movable part 42 rotatably connected to the fixed part 41, which improves the flexibility of the nozzle 3 and expands the cleaning range. The movable part 42 is slidably connected to the fixed part 41 through a sliding block 421 and a sliding groove 62 opened in the sleeve 6, further improving the flexibility of the nozzle 3. At the same time, the nozzles 32 on the multiple spray bars 31 in each group of nozzles 3 are opened at different positions, which allows each nozzle 32 to spray and clean the inner wall of the storage hopper 1 from different positions, improving the cleaning effect and efficiency. When flour is attached to the inner wall of the storage hopper 1, the gas generating component 5 is activated. The high-pressure gas generated by the gas generating component 5 enters the nozzle 3 through the nozzle 4 and is finally sprayed out from the nozzle 32. Because the nozzle 32 is set at an angle, the high-pressure gas will be sprayed toward the inner wall of the storage hopper 1, thereby breaking up and blowing off the flour adhering to the inner wall of the storage hopper 1, thus achieving the cleaning function of the storage hopper 1.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
