Abstract
Description
Technical Field
[0001] This utility model relates to the field of grain warehouse cleaning technology, and in particular to a new type of high-efficiency and environmentally friendly wide-channel combined screen. Background Technology
[0002] During the grain storage process, the grain needs to be cleaned and impurities removed. Ordinary cleaning machines have relatively narrow channels. When performing air separation, the grain layer is thick and the time is short due to space constraints. As a result, the grain is not cleaned thoroughly, the efficiency is low, and the cleaning effect is poor. Multiple cleanings are required, which leads to an excessively long cleaning process. In addition, the cleaning process is generally open, resulting in a lot of dust on site, which affects the environment and the health of the workers. Utility Model Content
[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a novel, highly efficient, and environmentally friendly wide-channel combined screen, which can solve the problems of low cleaning efficiency and environmental impact associated with ordinary cleaning machines.
[0004] This utility model discloses a novel high-efficiency and environmentally friendly wide-channel combined screen, comprising a grain and impurity dispersion system, a vibrating sieving system, a dust removal system, and a movable support. The grain dispersion system includes a loading hopper, a dispersion guide plate, an umbrella-shaped dispersion chute, and an air inlet grid, allowing grain and impurities to be evenly dispersed through the umbrella-shaped dispersion chute. The vibrating sieving system includes a screen, an impurity collection chute, a vibrating motor, screen support columns, support springs, a grain collection channel, a grain discharge port, and an impurity discharge port, enabling effective separation of grain and impurities as they pass through the screen. The dust removal system includes a cyclone separator, a fan, air ducts, an ash discharge port, an air duct volume regulating valve, an exhaust port, and an exhaust valve. Through circulating air, grain and impurities fall from the umbrella-shaped dispersion chute onto the screen for air separation. Impurities are separated by entering the dust removal system through the air ducts, preventing dust from escaping. The movable support includes a support frame and wheels, providing support and mobility.
[0005] The novel high-efficiency and environmentally friendly wide-channel combined screen according to the above embodiments of this utility model has at least the following beneficial effects:
[0006] The novel high-efficiency and environmentally friendly wide-channel combined screen provided in this embodiment of the utility model uses a grain and impurity dispersion system. The hopper collects grain and impurities, which fall into an umbrella-shaped dispersion chute. The grain is evenly dispersed by the dispersion guide plate and the umbrella-shaped dispersion chute. The fan is started to circulate the air in the air duct. The incoming air and the circulating air are supplemented through the air inlet grid. The grain and impurities are air-separated as they fall from the umbrella-shaped dispersion chute into the screen. The lighter impurities are input into the cyclone separator through the air duct. The dust removal function of the cyclone separator allows the impurities to settle at the ash discharge port. The impurities are separated and packaged by the airlock or movable plate.
[0007] Grain and impurities fall into the screen, and the screen vibrates due to the vibration motor, effectively separating the grain and impurities as they slide down the screen. The grain exits from the discharge port, which is equipped with an airlock or movable plate to prevent air leakage. Impurities are collected through an impurity collection chute and exit from the impurity discharge port, which is also equipped with an airlock or movable plate to prevent air leakage. The screen support columns and support springs support the grain and impurity dispersion system and the vibrating screening system. The movable support frame, with its support frame and wheels, provides support and mobility.
[0008] According to some embodiments of this utility model, the dispersing guide plate is installed on the umbrella-shaped dispersing slide. The dispersing guide plate is straight or arc-shaped and serves to disperse grain and impurities. The dispersing guide plate and the umbrella-shaped dispersing slide are made of wear-resistant materials.
[0009] According to some embodiments of this utility model, the hopper is made into a semi-enclosed shape to facilitate the input of grain into the hopper and the entry of circulating air into the hopper, and also to provide rain protection. Wear-resistant materials are installed at the grain drop section of the hopper to improve wear resistance.
[0010] According to some embodiments of this utility model, the movable support can be equipped with an electric walking device for easy movement.
[0011] According to some embodiments of this utility model, the screen is divided into upper and lower layers. The upper layer screens large impurities, and the lower layer screens small impurities. The lowest end of the upper screen has holes for collecting large impurities that lead to the impurity collection chute. The screen is arranged in sections and can be disassembled and pulled out for easy replacement.
[0012] According to some embodiments of this utility model, the air duct is equipped with an air volume regulating valve for adjusting the air volume. The air duct is equipped with an exhaust port and an exhaust valve. When air circulation is not required, the exhaust valve is opened and air is exhausted through the exhaust port. Wear-resistant material is installed on the inner wall of the duct to improve wear resistance.
[0013] According to some embodiments of this utility model, the grain unloading port, miscellaneous waste unloading port, and ash unloading port are equipped with airlocks or movable plates to prevent air leakage.
[0014] According to some embodiments of this utility model, the fan motor part is equipped with a conventional motor or a variable frequency motor, and the air volume is adjusted by the variable frequency motor.
[0015] According to some embodiments of this utility model, the feature is that the supporting spring has a column in the middle, the lower part of the column is smaller, and there is a hole larger than the column at the position of the support frame. When the spring breaks, the column is inserted into the position of the support frame and plays a supporting role.
[0016] According to some embodiments of the present invention, the impurity collecting chute is an inverted cone shape, with one side of the impurity collecting chute extending so that impurities are collected and discharged from one side. Wear-resistant material is installed on the inner wall of the impurity collecting chute to improve wear resistance, and the impurity collecting chute has a discharge port to prevent clogging.

[0033] Reference Figures 1 to 3This utility model discloses a novel high-efficiency and environmentally friendly wide-channel combined sieve, comprising a grain and impurity dispersion system 100, a vibrating sieving system 200, a dust removal system 300, and a movable support 400. It also relates to grain 500 and impurities 600. The grain and impurity dispersion system 100 includes a hopper 110, a dispersion guide plate 120, an umbrella-shaped dispersion chute 130, and an air inlet grid 140, allowing the grain 500 and impurities 600 to be uniformly dispersed through the umbrella-shaped dispersion chute 130. The vibrating sieving system 200 includes a screen 210, an impurity collection chute 220, a vibrating motor 230, and a sieve support column 240. The system includes a support spring 250, a grain collection channel 260, a grain unloading port 270, and a waste unloading port 280, which effectively separate grain 500 and impurities 600 as they pass through the screen 210. The dust removal system 300 includes a cyclone separator 310, a fan 320, an air duct 330, and an ash unloading port 340. Through circulating air, grain 500 and impurities 600 fall from the umbrella-shaped dispersion chute 130 onto the screen 210 for air separation. Impurities 600 enter the dust removal system 300 through the air duct 330 for separation, and dust is prevented from being blown out. The movable support 400 includes a support frame 410 and wheels 420, which serve to support and move the grain.
[0034] It is understood that the novel high-efficiency and environmentally friendly wide-channel combined screen provided in this utility model embodiment collects grain 500 and impurities 600 through the grain and impurity dispersion system 100 and the hopper 110. The grain 500 and impurities 600 fall into the umbrella-shaped dispersion chute 130 and are evenly dispersed by the dispersion guide plate 120 and the umbrella-shaped dispersion chute 130. The fan 320 is started to circulate the air in the air duct 330. The air entering and circulating air are supplemented through the air inlet grid 140. The grain 500 and impurities 600 fall from the umbrella-shaped dispersion chute 130 into the screen 210 for air separation. The lighter impurities 600 are input into the cyclone 310 through the air duct 330. The dust removal function of the cyclone 310 causes the impurities 600 to settle at the ash discharge port 340. The impurities 600 are separated and packaged by the airlock or movable plate.
[0035] Grain 500 and impurities 600 fall into the screen. The vibrating motor 230 causes the screen 210 to vibrate, effectively separating the impurities 600 as they slide down the screen 210. The grain 500 exits from the discharge port 270, where an airlock or movable plate is installed to prevent air leakage. The impurities 600 are collected by the impurity collection chute 220 and exit from the discharge port 280, where an airlock or movable plate is installed to prevent air leakage. The screen support column 240 and support spring 250 support the grain and impurity dispersion system 100 and the vibrating screening system 200. The movable support 400 provides support and movement via the support frame 410 and wheels 420.
[0036] Furthermore, according to some embodiments of the present invention, the dispersing guide plate 120 is installed on the umbrella-shaped dispersing slide 130. The dispersing guide plate 120 is straight or arc-shaped, guiding the grain 500 and impurities 600 to slide down along the umbrella-shaped dispersing slide 130, thereby dispersing the grain 500 and impurities 600. The dispersing guide plate 120 and the umbrella-shaped dispersing slide 130 are made of wear-resistant materials.
[0037] Understandably, the hopper 110 is made into a semi-enclosed structure to facilitate the input of grain 500 and impurities 600 into the hopper 110, as well as the input of circulating air into the hopper 110, and to provide rain protection. Wear-resistant materials are installed at the grain drop section of the hopper 110 to improve wear resistance.
[0038] Preferably, according to some embodiments of the present invention, the mobile support 400 may be equipped with a remote-controlled electric walking device and a steering device for easy movement.
[0039] Furthermore, according to some embodiments of this utility model, the screen 210 is divided into upper and lower layers. The upper layer screens large impurities, and the lower layer screens small impurities. The lowest end of the upper screen has holes for collecting large impurities that lead to the impurity collection chute 220. The screen 210 is arranged in blocks and fixed with slots or screws. It can be disassembled and pulled out for easy replacement.
[0040] Furthermore, according to some embodiments of this utility model, the air duct 330 is provided with an air duct air volume regulating valve 350 for regulating the air volume. The air duct 330 is provided with an exhaust port 360 and an exhaust valve 370. When air circulation is not required, the exhaust valve 370 is opened and exhaust is performed through the exhaust port 360. Wear-resistant materials are installed on the inner wall of the duct to improve wear resistance.
[0041] Furthermore, according to some embodiments of this utility model, airlocks or movable plates are installed on the grain unloading port 270, the miscellaneous waste unloading port 280, and the ash unloading port 340 to prevent air leakage.
[0042] Furthermore, according to some embodiments of this utility model, the motor part of the fan 320 is equipped with a regular motor or a variable frequency motor, and the air volume is adjusted by the variable frequency motor to save electricity.
[0043] Furthermore, according to some embodiments of this utility model, the support spring 250 has a column in the middle, the lower part of the column is smaller, and there is a hole larger than the column at the position of the support frame 410. When the spring breaks, the column is inserted into the position of the support frame 410 and plays a supporting role.
[0044] It is understandable that the impurity 600 collecting chute is an inverted cone shape, and the impurity collecting chute 220 extends to one side, so that the impurities 600 collect and exit from one side. The inner wall of the impurity collecting chute 220 is equipped with wear-resistant material to improve wear resistance, and the impurity 600 collecting chute has anti-clogging openings.
[0045] It should be noted that, in this embodiment of the utility model, the arrangement of the air duct 330 can be determined according to the actual situation, and is not specifically limited here.
[0046] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
