Description

A new type of environmentally friendly grain vibration cleaning device Technical Field

[0001] This utility model relates to the technical field of grain cleaning and impurity removal devices, and in particular to a new type of environmentally friendly grain vibration cleaning device. Background Technology

[0002] In grain storage operations, the cleaning process is the most polluting stage. How to avoid or reduce pollution during grain cleaning is a practical problem that grain machinery manufacturers and grain storage enterprises must actively address and strive to solve. Currently, there are two common dust removal devices for grain vibration cleaning equipment on the market: the Shakel dust collector and the pulse dust collector. The Shakel dust collector has strong suction and good chaff removal effect, but the exhaust port is heavily polluted with dust, and dust and a small amount of chaff are released into the air, causing serious air pollution, a harsh working environment, and harming the health of workers. The pulse dust collector has good dust removal effect, but poor chaff removal effect, often requiring secondary chaff removal, which is not only time-consuming and labor-intensive but also increases processing costs. Developing a new type of dust removal device that combines the advantages of both Shakel and pulse dust collectors would be of great practical significance for improving grain cleaning quality and reducing pollution, but so far there have been no relevant public reports. Summary of the Invention

[0003] In view of the above situation and to overcome the defects of the existing technology, the purpose of this utility model is to provide a new type of environmentally friendly grain vibration cleaning device, which can effectively solve the problems of poor environmental protection when using sand-clone dust removal devices alone and poor chaff removal effect of pulse dust collectors.

[0004] To achieve the above objectives, the technical solution provided by this utility model is a novel environmentally friendly grain vibration cleaning device, comprising a base, a vibrating screen, a sand-clone dust removal device, and a pulse dust removal device. Four inflatable wheels are mounted below the base. The vibrating screen, sand-clone dust removal device, and pulse dust removal device are respectively mounted on the base. The screen surface of the vibrating screen is inclined, and the lower grain discharge port is connected to one end of a suction box. The upper part of the suction box is connected to the suction port of the sand-clone dust removal device. A grain conveying device is mounted on the base below the suction box. The grain outlet below the suction box is located directly above the inlet of the grain conveying device. The outlet of the sand-clone dust removal device is connected to the inlet of the pulse dust removal device via a connecting pipe. The vibrating screen, sand-clone dust removal device, and pulse dust removal device are each connected to a controller.

[0005] This utility model has a simple structure, a scientific and reasonable design, and is easy to use. It has a good effect on dust removal and chaff removal, effectively ensuring the cleanliness of grain and improving grain quality. The dust generated during the cleaning process is collected in real time, which not only protects the working environment but also avoids dust pollution, protects the health of workers, and has good social and economic benefits. Attached Figure Description

[0006] Figure 1 is a schematic diagram of the structure of this utility model. Detailed Implementation

[0007] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings and specific circumstances.

[0008] As shown in the attached drawings, a novel environmentally friendly grain vibration cleaning device includes a base, a vibrating screen, a sand-clone dust removal device, and a pulse dust removal device. Four inflatable wheels 12 are mounted below the base 5. The base 5 is respectively equipped with a vibrating screen 1, a sand-clone dust removal device 3, and a pulse dust removal device 6. The screen surface of the vibrating screen 1 is inclined, and its lower grain discharge port 11 is connected to one end of a suction box 2. The upper part of the suction box 2 is connected to the suction port of the sand-clone dust removal device 3. A grain conveying device 4 is mounted on the base 5 below the suction box 2. The grain outlet 21 below the suction box 2 is located directly above the grain conveying device 4. The air outlet of the sand-clone dust removal device 3 is connected to the air inlet of the pulse dust removal device 6 via a connecting pipe 61. The vibrating screen 1, the sand-clone dust removal device 3, and the pulse dust removal device 6 are all connected to a controller 7.

[0009] To ensure better implementation results, the suction box 2 is a hollow box with an inverted trumpet shape at the bottom. A sealing strip is installed at the connection between the grain discharge port 11 of the vibrating screen 1 and the suction box 2. A rotatable baffle is installed on the horizontal plane along the long side inside the suction box 2, which can freely adjust the wind force.

[0010] The aforementioned Shaklon dust removal device 3 has two units arranged side by side. The air inlets of the two Shaklon dust removal devices 3 are respectively connected to the top of the air suction box 2, and the air outlets are respectively connected to the connecting pipe 61.

[0011] The vibrating screen 1 mentioned is either the TQLZ220*240-EP type environmentally friendly vibrating screen produced by Anhui Yunlong Grain Machinery Co., Ltd. or the JLZD2024A type mobile vibrating screen produced by Anhui Juli Grain Machinery Technology Co., Ltd., but is not limited to these models. Any other vibrating screen that can achieve the same function falls within the protection scope of this utility model.

[0012] The aforementioned Shaclon dust removal device 3 is either the JC-XFCCQ Shaclon high-efficiency dust collector produced by Cangzhou Jiachen Environmental Protection Machinery Equipment Co., Ltd., or the TAG-type Shaclon dust collector produced by Hebei Zengyu Environmental Protection Technology Co., Ltd. There is one Shaclon dust removal device on each side, and both are equipped with a 5.5KW explosion-proof centrifugal fan. However, it is not limited to these models. Any other Shaclon dust removal devices that can achieve the same function fall within the protection scope of this utility model.

[0013] The pulse dust collector 6 mentioned above is either the PPCS-4 air box pulse bag dust collector produced by Guangzhou Yikang Environmental Protection Equipment Co., Ltd. or the HMC type pulse bag dust collector produced by Botou Yuehong Environmental Protection Equipment Co., Ltd., but is not limited to these models. Any other pulse dust collector that can achieve the same function falls within the protection scope of this utility model.

[0014] The controller 7 is a PLC controller.

[0015] The screen surface of the vibrating screen 1 is inclined at an angle of 12º to the horizontal plane.

[0016] The grain conveying device 4 is a belt conveyor.

[0017] In practical use, the four pneumatic wheels 12 below the base 5, two of which are directional adjustment wheels below the grain inlet of the vibrating screen 1, and the other two are fixed straight-moving wheels. The directional adjustment wheels can adjust the direction of the grain outlet of the grain conveying device as needed. The screen surface of the vibrating screen 1 has an inclination angle of 12º, with the raised end being the grain inlet and the non-raised end being the grain outlet. The vibrating screen 1 has two layers of screens. The aperture of the upper screen is generally 5-8 times the size of the grain stalk, while the aperture of the lower screen is smaller than the grain particles. The upper screen cleans large impurities such as wheat, corn, and rice straw, soil clods, and stones, while the lower screen cleans small inorganic impurities. Guide plates are installed on both sides of the grain outlet of the vibrating cleaning device to facilitate the grain flowing out in the designed direction. Grain flowing out of the discharge port 11 of the vibrating screen 1 enters the suction box 2. The sand-clone dust removal device 3 uses the negative pressure principle to suck the chaff and dust in the grain in the suction box 2 into the sand-clone. The grain is then sent to the grain conveying device 4 through the grain outlet 21 below the suction box 2, and then to the grain conveying equipment in the next stage for grain storage. The chaff and some dust fall into the sand-clone dust collection chamber and are discharged through the auger (not shown in the figure) below the dust collection chamber. At the same time, some dust and a small amount of chaff are discharged with the air outlet of the sand-clone dust removal device 3 and blown into the pulse dust removal device 6 through the connecting pipe 61. The pulse dust removal device 6 collects the dust and a small amount of chaff and then discharges them through the two discharge ports below.

[0018] This utility model has a simple structure, a scientific and reasonable design, and is easy to use. The vibrating screen cleans large impurities such as grain straw, soil clods, and stones, as well as small inorganic impurities. After the sand-clone dust removal device cleans the chaff and some dust, some dust and a small amount of chaff are connected to the pulse dust removal device through the air outlet. This overcomes the drawback of the sand-clone dust removal device directly discharging some dust and a small amount of chaff into the air, avoiding dust pollution, effectively ensuring the cleanliness of the grain, and improving the quality of the grain. The dust generated during the cleaning process is collected in real time, which protects the working environment, avoids dust pollution, and protects the health of the workers. It has a wide range of applications and can be used for cleaning granular grains such as rice, wheat, and corn, as well as oilseeds, with good social and economic benefits.

[0019] It should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any person skilled in the art who can make changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model's technical solution shall fall within the protection scope of the present utility model.
