Description

Technical Field

[0001] The invention relates to the field of wheat processing, and in particular to an automatic flour cleaning machine used for wheat experimental processing. Background Art Wheat is an annual or biennial herbaceous plant of the Gramineae family and the genus Triticeae. The culms are erect and clustered, the leaf sheaths are loosely phimotic, the leaf ligules are membranous, and the leaves are long lanceolate. The spike inflorescence is erect, the spikelets contain many small flowers, the glumes are oval, the lemmas are oblong-lanceolate, and the palea is almost the same length as the lemma. The flowering and fruiting period is from May to July.

[0002] Wheat flour milling refers to the process of processing clean wheat that has been cleaned and conditioned into finished flour that meets national standards with the help of certain processes and equipment. In this process, the endosperm, bran (pericarp and seed coat) and embryo in the wheat grains need to be separated and ground into flour. The main process of wheat flour milling is to separate the endosperm from the germ and bran after the wheat grains are cleaned and the moisture is adjusted, and then the endosperm is ground into flour.

[0003] In the prior art, before the wheat husk peeling operation, it is usually necessary to use mechanical equipment such as a vibrating screen to screen the wheat particle size to ensure the stable operation effect of the subsequent wheat husk peeling operation. During this screening operation, the dust, fluff and other impurities attached to the wheat particles can be removed and cleaned by configuring an airflow drive structure to ensure the cleanliness of the wheat. Although the above-mentioned operation can meet the particle size screening and powder cleaning and impurity removal operations before wheat processing, most of them use the airflow carrying impurities such as dust and fluff to be directly discharged into the surrounding ambient air, which is easy to affect the surrounding air quality. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an automatic powder purifier for wheat experimental processing, which can adsorb, filter and independently discharge the dust removal airflow, in view of the shortcomings of the prior art mentioned in the background technology.

[0005] The present invention is achieved through the following technical scheme: it includes a machine body, a feed port is provided on one end wall of the machine body, at least one screening net is evenly distributed in the machine body, and a corresponding number of discharge channels are provided to match the screening net, and it is characterized in that a rotatable dust filter assembly is provided in the machine body above the screening net, an air guide assembly is provided in the machine body below the screening net, an air inlet end is provided on one side of the air guide assembly, and an exhaust end is provided above the dust filter assembly, wherein the air guide assembly is used to guide the air entering from the air inlet end to pass through the screening net and the dust filter assembly in sequence to form an airflow to the exhaust end, and the dust filter assembly is used to absorb and collect the dust driven by the airflow and discharge it independently.

[0006] By adopting the above technical solution, the air inlet end guides air into the machine body, and the air outlet end guides the air in the machine body out, thereby forming a circulating air flow. This circulating air flow can successively pass through the screening mesh and the dust filtering component under the action of the air guiding component, for purging and cleaning sundries such as dust and fluff adhering to the surface of wheat during the screening process on the screening mesh, and using the dust filtering component to filter and collect the purged sundries.

[0007] In a specific technical solution, there are three screening meshes, namely the primary screening mesh, the secondary screening mesh, and the tertiary screening mesh, and their screening densities increase gradually from top to bottom.

[0008] By adopting the above technical solution, the three screening meshes can screen wheat grains into four different specifications of particle sizes.

[0009] In a specific technical solution, there are five discharge channels, namely: the first discharge channel adapted and connected to the upper end of the primary screening mesh, the second discharge channel adapted and connected to the upper end of the secondary screening mesh, the third discharge channel adapted and connected to the upper end of the tertiary screening mesh, the fourth discharge channel adapted and connected to the lower end of the tertiary screening mesh, and the dust discharge channel connected to the dust filtering component.

[0010] By adopting the above technical solution, four of the five discharge channels are used to discharge wheat of four different specifications of particle sizes, and the other dust discharge channel is used to discharge the sundries filtered and collected by the dust filtering component.

[0011] In a specific technical solution, the dust filtering component includes an annular flexible dust filtering net, drive shafts engaged at both ends inside the flexible dust filtering net, and a cleaning roller located on one side of the flexible dust filtering net for cleaning.

[0012] By adopting the above technical solution, the cleaning roller can clean the flexible dust filtering net in circular motion to ensure that the flexible dust filtering net can be recycled.

[0013] In a specific technical solution, fans are installed at both the air inlet end and the air outlet end, and air nets are installed on one side or both sides of the fans.

[0014] By adopting the above technical solution, the air net is used to filter the air flow passing through the air inlet end and the air outlet end, to avoid larger debris particles from damaging the fans.

[0015] In a specific technical solution, the air guiding component includes a wind guiding plate slidably connected to the discharge platform. Sliders are formed on both sides of the lower end of the wind guiding plate, and electric slide rails are provided at the corresponding positions on the discharge platform for the sliders. The wind guiding plate is slidably connected along the electric slide rails under the action of the sliders.

[0016] By adopting the above technical solution, the air deflector capable of displacement adjustment can guide the air flow according to the specific screening passing position of the screening mesh, thereby promoting the blowing and dust removal effect of the air flow.

[0017] In a specific technical solution, magnetic attraction components are evenly arranged in the primary discharge channel, secondary discharge channel, and tertiary discharge channel. The magnetic attraction component includes a control rod slidably connected in the discharge channel. A plurality of magnetic attraction rods are connected to the lower end of the control rod. The control rod is internally provided with a power source for controlling the magnetic attraction switch of the magnetic attraction rods.

[0018] By adopting the above technical solution, the magnetic attraction rods can generate a magnetic attraction effect after being powered on, and can magnetically adsorb and collect the metal substances doped in the wheat grains passing through the corresponding discharge channels.

[0019] In a specific technical solution, a slider is fixedly installed at the upper end of the control rod. An adjustment sliding groove is opened at the corresponding position of the inner top wall of the discharge channel and the slider. The control rod is slidably connected along the adjustment sliding groove under the action of the slider.

[0020] By adopting the above technical solution, the adjustment sliding groove can allow the control rod to adjust its displacement under the action of the slider to adapt to different blanking environments.

[0021] In a specific technical solution, an observation window is embedded on the side wall of the machine body. The position of the observation window corresponds to the primary discharge channel, secondary discharge channel, and tertiary discharge channel.

[0022] By adopting the above technical solution, the observation window allows the staff to directly observe the working state of the magnetic attraction components in the blanking channels.

[0028] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] In the prior art, for the equipment of wheat pre-processing, in order to achieve a stable operation effect for wheat shelling, it is common to use a vibrating screen to screen the wheat by particle size to ensure subsequent processing of wheat with different particle sizes for peeling and shelling. During this screening operation, it is also common to be equipped with a blower to blow the wheat during screening, so that the impurities mixed in the wheat can be blown and separated, improving the cleanliness of the wheat and reducing the workload of subsequent cleaning and processing. However, during this operation, most of the blowing airflows are directly discharged into the surrounding ambient air, so it is easy to affect the physical health of the surrounding workers. To solve this problem, the following technical solutions are proposed.

[0030] Please refer to Figures 1 - 3 , an automatic flour purifier for wheat test processing in this embodiment, includes a machine body. An inlet is provided on one end wall of the machine body. There is at least one screening mesh evenly distributed in the machine body, and a corresponding number of discharge channels are provided in matching with the screening mesh. It is characterized in that a rotatable dust filtering component is provided above the screening mesh in the machine body, a wind guiding component is provided below the screening mesh in the machine body, an air inlet end is provided on one side of the wind guiding component, and an air outlet end is provided above the dust filtering component. Among them, the wind guiding component is used to guide the air entering from the air inlet end to form an air current passing through the screening mesh and the dust filtering component in sequence and discharging to the air outlet end, and the dust filtering component is used to adsorb and collect the dust carried by the air current and discharge it independently; The embodiment of the present invention provides an automatic flour purifier for wheat test processing that can adsorb, filter and discharge the dust removal air current independently, solving the problem in the prior art that during the operation of screening the wheat particle size and cleaning and removing impurities, most of the airflows carrying impurities such as dust and fluff are directly discharged into the surrounding ambient air, which is easy to affect the surrounding air quality. The general idea of this embodiment to solve the above problem is: by configuring a rotatable dust filtering component on the air current flow path to filter and clean the air current carrying impurities such as dust and fluff. This dust filtering component has a self-cleaning effect and can stably filter and clean the continuously flowing air current, and uses an independent discharge channel to guide and discharge the impurities filtered and cleaned by the dust filtering component to avoid affecting the surrounding air quality.

[0031] Please refer to Figure 2, in a specific embodiment, there are three screening meshes, namely a primary screening mesh, a secondary screening mesh, and a tertiary screening mesh, and their screening densities increase gradually from top to bottom; there are five discharge channels, namely: a first discharge channel adapted to communicate with the upper end of the primary screening mesh, a second discharge channel adapted to communicate with the upper end of the secondary screening mesh, a third discharge channel adapted to communicate with the upper end of the tertiary screening mesh, a fourth discharge channel adapted to communicate with the lower end of the tertiary screening mesh, and a dust discharge channel communicating with the dust filtering component; in this embodiment, wheat materials enter the machine body through the feed inlet, first fall on the primary screening mesh, and after passing through multiple screenings of the primary screening mesh, the secondary screening mesh, and the tertiary screening mesh in sequence, they can enter the first discharge channel, the second discharge channel, the third discharge channel, and the fourth discharge channel adapted to them in different particle sizes, and then be discharged from the machine body; The screening mesh described here can use a vibrating screen to ensure its screening efficiency and effect.

[0032] Please refer to Figures 2 - 4 , in a specific embodiment, fans are installed at both the air inlet end and the air outlet end, and air nets are installed on one or both sides of the fans; in this embodiment, the air inlet end can extract and discharge the air outside the machine body into the machine body, while the air outlet end can extract and discharge the air inside the machine body to the outside of the machine body. Therefore, an air flow can be formed inside the machine body, and by means of this air flow, it can penetrate through the tertiary screening mesh, the secondary screening mesh, and the primary screening mesh in sequence to blow and remove impurities such as dust and fluff attached to the surface of wheat during the screening operation.

[0033] Please refer to Figure 2 and Figure 3 , in a specific embodiment, the dust filtering component includes an annular flexible dust filtering net, drive shafts engaged at both ends inside the flexible dust filtering net, and a cleaning roller located on one side of the flexible dust filtering net for cleaning; combining the above embodiment, the air flow will blow the impurities such as dust and fluff removed by blowing towards the flexible dust filtering net, and the flexible dust filtering net filters the air flow, so that the dust and fluff it carries can be filtered and collected on the flexible dust filtering net. The drive shafts can drive the flexible dust filtering net to rotate, so that the filtering working surface of the flexible dust filtering net can be continuously updated to ensure the stable effect of its filtering operation. Moreover, the cleaning roller located on one side of the flexible dust filtering net can scrape and clean the rotating flexible dust filtering net, so that the impurities filtered and collected by the flexible dust filtering net can fall off and enter the dust discharge channel to be independently discharged from the machine body, while meeting the cyclic filtering and collection use of the flexible dust filtering net.

[0034] In a specific embodiment, when the wheat particle size is generally larger, the specific screening throughput of the first-level screening net will be extended backward. When the wheat particle size is generally smaller, the specific screening throughput of the first-level screening net will be advanced. Therefore, the specific screening throughput of the first-level screening net is affected by the general size change of the wheat particle size. Based on this technical problem, the specific purge path of the airflow needs to be adjusted with the position of the specific screening throughput of the screening net to achieve the maximum benefit of the airflow purge effect. The following technical means are proposed to achieve this technical effect.

[0035] The present invention meets the adjustment requirements of the airflow sweeping position by configuring a slidable and adjustable air guide component in the body, please refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 The air guide assembly includes an air guide plate slidably connected to the discharge platform, and sliders are formed on both sides of the lower end of the air guide plate. An electric slide rail is provided on the discharge platform corresponding to the slider, and the air guide plate is slidably connected along the electric slide rail under the action of the slider; in this embodiment, the air guide plate can be displaced and adjusted based on the action of the slider and the electric slide rail, so that the airflow entering the air inlet end can be guided to different blowing positions, thereby meeting the maximum benefit of the airflow blowing effect in the above technical problem.

[0036] In a specific embodiment, if metal substances such as broken iron are mixed in the wheat during the screening and powder cleaning operation, a separate magnetic suction device is required in the subsequent process to clean the broken iron and other metal substances. Based on this technical problem, the following technical means are proposed.

[0037] The present invention arranges magnetic suction components in the primary discharge channel, the secondary discharge channel and the tertiary discharge channel to magnetically absorb the sieved wheat particles, and can magnetically absorb and clean the metal substances such as broken iron mixed therein. Figure 3 , Figure 4 , Figure 5 and Figure 7 The magnetic suction component includes a control rod slidably connected to the discharge channel, and a plurality of magnetic suction rods are connected to the lower end of the control rod. The control rod has a built-in power supply for controlling the magnetic suction switch of the magnetic suction rod. In this embodiment, the magnetic suction rod adopts the material properties of an electromagnet, and the control rod controls the circuit connection of the magnetic suction rod, so that the magnetic suction rod can produce a magnetic suction effect during operation, and magnetically absorb and clean metal substances such as broken iron mixed in wheat.

[0038] In addition, in order to meet the vibration feeding effects of different vibrating screens, the present invention proposes to use a sliding connection method to connect the magnetic suction component to meet different vibration feeding effects. For details, please refer to Figure 3 , Figure 4 andFigure 7 At the upper end of the control rod, a slider is fixedly installed. At the corresponding position of the inner top wall of the discharge channel, an adjustment chute is provided. The control rod is slidably connected along the adjustment chute under the action of the slider. In this embodiment, the control rod can adjust its sliding displacement based on the connection between the slider and the adjustment chute, so as to change its specific magnetic attraction range. For example, when the vibration force of the vibrating screening mesh is small, resulting in a short throwing distance of wheat when it enters the corresponding discharge channel, the magnetic attraction component can be adjusted closer to the vibrating screening mesh to ensure that its magnetic attraction range can meet the magnetic attraction cleaning effect on the wheat during the throwing process. If the vibration force of the vibrating screening mesh is large, resulting in a long throwing distance of wheat when it enters the corresponding discharge channel, the magnetic attraction component can be adjusted away from the vibrating screening mesh, also meeting the magnetic attraction cleaning effect on the wheat during the throwing process.

[0039] Finally, please refer to Figure 1 An observation window is embedded on the side wall of the machine body. The position of the observation window corresponds to the primary discharge channel, the secondary discharge channel, and the tertiary discharge channel. The observation window enables the staff to directly observe the specific magnetic attraction effect and operation range of the magnetic attraction component outside the machine body, facilitating timely adaptation and adjustment. It can also observe the adsorption amount of the magnetic attraction component, facilitating timely cleaning of the adsorbed metal substances such as broken iron.

[0040] A support is fixedly installed at the lower end of the machine body. The support is used to increase the overall operation height of the machine body, facilitating the collection of wheat particles or dust impurities discharged through each channel.
