Abstract
Description
Technical Field
[0001] This utility model relates to the field of flour storage technology, and in particular to a flour storage rack. Background Technology
[0002] Flour, as a typical powdery grain product, is highly hygroscopic and easily affected by environmental humidity, temperature, and air circulation. In actual storage, to facilitate loading, unloading, and stacking, flour is usually stored in bags and stacked in multiple layers manually or mechanically. Traditional flour storage methods generally involve installing ventilation windows or exhaust fans inside the warehouse to achieve overall air circulation and reduce indoor relative humidity. However, this overall ventilation method has limited effectiveness within the flour bag stacks, especially when the stacks are high, dense, or the warehouse space is limited, making it difficult to establish effective air exchange paths between the flour bags.
[0003] Specifically, due to the close stacking of flour sacks, localized air layers can easily form. Under conditions of high ambient humidity or significant diurnal temperature variations, the humidity inside the stack is often higher than the overall humidity of the warehouse. Ventilation is even worse in the central area of the stack, making it easier for moisture to accumulate and condense. This leads to dampness between flour sacks or between flour sacks and their supports, further causing the flour to clump and form lumps. In severe cases, it can even result in mold and a decline in quality. Utility Model Content
[0004] The purpose of this invention is to provide a flour storage rack to improve ventilation between stacked flour.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A flour storage rack includes a vertical support and a base plate. Several pipe assemblies are slidably connected to the vertical support. The pipe assemblies are stacked one on top of the other. Adjacent pipe assemblies are connected by a magnetic attraction mechanism. A lifting mechanism is installed between the topmost pipe assembly and the vertical support. Each pipe assembly includes a breathable vent pipe with air holes around its periphery. A row of vent pipes is provided between every two layers of flour.
[0007] Two adjacent pipe assemblies are defined as the upper assembly and the lower assembly, respectively. The magnetic attraction mechanism includes a ferromagnetic plate and an electromagnet that can attract magnetic force. The ferromagnetic plate is fixed at the upper part of the pipe assembly and the electromagnet is fixed at the lower part. The electromagnet of the upper assembly can attract the ferromagnetic plate of the lower assembly.
[0008] The lifting mechanism includes a rotary motor fixed to the top of the vertical support and a winding wheel rotatably connected to the top of the vertical support. A pull rope is wound on the winding wheel, and the free end of the pull rope is fixed to the uppermost pipe assembly.
[0009] The pipeline assembly includes two symmetrically arranged diversion boxes, which are slidably connected to the vertical support. Several vent pipes are connected between the two diversion boxes. Each diversion box has a diversion cavity, a first hole and a second hole communicating with the diversion cavity. The second hole is connected to the vent pipe, and the first hole is connected to the external environment or an airflow dryer.
[0010] The airflow dryer includes a fan and an airflow dryer. The exhaust port of the fan is connected to the air inlet of the airflow dryer, and the exhaust port of the airflow dryer is connected to the first hole.
[0011] The top surface of the shunt box is fixed with a ferromagnetic plate and the bottom surface is fixed with an electromagnet. Each pipe assembly corresponds to a control switch, and each control switch can control the energization or de-energization of all electromagnets below a pipe assembly.
[0012] The flour storage rack proposed in this utility model has the following advantages: By setting a row of ventilated pipes with air holes between every two layers of flour bags, this utility model can effectively achieve directional ventilation inside the stacking structure, avoid the problem of moisture accumulation caused by air stagnation between bags, improve the ventilation efficiency during the storage of stacked flour, reduce the problem of caking and clumping caused by poor ventilation, and improve the quality stability of flour during the storage process.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0018] Reference Figures 1-3A flour storage rack includes a vertical support 1 and a base plate 2. Several pipe assemblies 3 are slidably connected to the vertical support 1. The multiple pipe assemblies 3 are stacked one on top of the other. Adjacent pipe assemblies 3 are connected by a magnetic attraction mechanism. A lifting mechanism is installed between the uppermost pipe assembly 3 and the vertical support 1. The pipe assembly 3 includes a breathable vent pipe 13. The vent pipe 13 has air holes 14 around its periphery. A row of vent pipes 13 is provided between every two layers of flour.
[0019] Multiple pipe components 3 are connected by a magnetic attraction mechanism. After one layer of flour bags is stacked, the bottommost pipe component 3 of the upper layer is released by the magnetic attraction mechanism, causing it to fall above the newly stacked flour bags. This achieves a row of ventilation pipes 13 between every two layers of flour bags for directional ventilation between adjacent flour bags.
[0020] When retrieving flour, the operator first removes the top layer of flour bags. Then, the lifting mechanism pulls the corresponding pipe assembly 3 upwards via a rope, and the magnetic attraction mechanism lifts the corresponding pipe assembly 3. After lifting, the operator continues to retrieve the second layer of flour bags. This cycle is repeated to achieve layer-by-layer lifting of the pipe assembly 3, ensuring that the ventilation pipe 13 between any two layers of flour bags does not interfere with the retrieval of the next layer of flour during the material retrieval process.
[0021] This invention effectively achieves directional ventilation inside the stacking structure by setting a row of ventilation pipes 13 with air holes 14 between every two layers of flour bags, avoiding the problem of moisture accumulation caused by air stagnation between bags, improving the ventilation efficiency during the storage of stacked flour, reducing the problems of caking and clumping caused by poor ventilation, and improving the quality stability of flour during storage.
[0022] Two adjacent pipe components 3 are defined as the upper component and the lower component, respectively. The magnetic attraction mechanism includes a ferromagnetic plate 8 and an electromagnet 9 that can attract magnetic force. The ferromagnetic plate 8 is fixed at the upper part of the pipe component 3 and the electromagnet 9 is fixed at the lower part. The electromagnet 9 of the upper component can attract the ferromagnetic plate 8 of the lower component.
[0023] When stacking flour bags, after each layer of flour bags is stacked, a ventilation pipe assembly 3 should be placed above that layer of flour bags. At this time, simply de-energize the electromagnet 9 corresponding to the second-to-last pipe assembly 3 from the top. The electromagnet 9 and the ferromagnetic plate 8 of the pipe assembly 3 below it will lose their attraction. The bottom pipe assembly 3 will then detach from the adsorption state and fall to the top of the newly stacked flour bags under the action of gravity.
[0024] The lifting mechanism includes a rotary motor 4 fixed to the top of the vertical support 1, a winding wheel 5 rotatably connected to the top of the vertical support 1, a pull rope 6 wound on the winding wheel 5, and the free end of the pull rope 6 fixed to the uppermost pipe assembly 3.
[0025] refer to Figure 1 When stacking flour, each time a layer of flour is stacked, the rotating motor 4 drives the winding wheel 5 to rotate clockwise, causing the pull rope 6 to move downwards, supporting the bottom pipe assembly 3 on the top layer of flour. Then, the electromagnet 9 of the second to last pipe assembly 3 is de-energized, and the pull rope 6 is moved upwards. The above process is repeated to complete the stacking of multiple layers of flour.
[0026] When flour needs to be taken out, the top layer of flour is removed, and then the winding wheel 5 rotates forward to make the pull rope 6 move downward. When the two adjacent ferromagnetic plates 8 and electromagnets 9 of the two pipe components 3 below come into contact, the electromagnet 9 is energized, and then the pull rope 6 moves upward to pull the lower pipe components 3 upward. The above process is repeated to complete the removal of flour layer by layer.
[0027] In one implementation, the piping assembly 3 includes two symmetrically arranged distribution boxes 7, which are slidably connected to the vertical support 1. Several vent pipes 13 connect the two distribution boxes 7. Each distribution box 7 has a distribution cavity 10, a first hole 11 communicating with the distribution cavity 10, and a second hole 12. The second hole 12 connects to the vent pipes 13, and the first hole 11 connects to the external environment or an airflow dryer. Through the movement of airflow inside the storage chamber, some airflow can enter between adjacent flour particles through the vent pipes 13, achieving a certain drying effect.
[0028] To improve the drying effect, the airflow dryer includes a fan and an airflow dryer. The exhaust port of the fan is connected to the air inlet of the airflow dryer, and the exhaust port of the airflow dryer is connected to the first hole 11.
[0029] An airflow is generated by a fan. After being dried by the airflow dryer, the airflow enters the distribution box 7. After passing through the distribution box 7 and the vent pipe 13, it is discharged from another distribution box 7. The dried airflow carries away the moisture from the adjacent flour bags, achieving a better drying effect.
[0030] In one specific implementation, a ferromagnetic plate 8 is fixedly connected to the top surface of the distribution box 7, and an electromagnet 9 is fixedly connected to the bottom surface. Each pipe assembly 3 corresponds to a control switch, and each control switch can control the energization or de-energization of all electromagnets 9 below a pipe assembly 3. When stacking flour, the control switches control the energization or de-energization of the electromagnets corresponding to each pipe assembly 3 to achieve magnetic attraction or release.
[0031] As one implementation method, the vent pipe 13 can be made of nylon, which has a certain degree of flexibility and rigidity.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solution and utility model concept disclosed in the present utility model should be included within the protection scope of the present utility model.
