Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of onion processing equipment, specifically a cleaning and impurity removal device for onion processing. Background Technology
[0002] Onions are biennial herbaceous plants belonging to the genus Allium in the family Amaryllidaceae. Onion roots are fibrous and fibrous, and the stem is shortened into a disc, which is flat and conical. The leaves consist of two parts: the leaf blade and the leaf sheath. The edible part grows underground, and whether it is dug by hand or harvested by machine, it is inevitable that it will contain soil and other impurities. In addition, the outer skin of onions is easy to peel off. The existing onion washing equipment used in the processing usually consists of multiple washing tanks for graded washing, which requires a large amount of washing water. Therefore, certain improvements are needed. Utility Model Content
[0003] To address the above technical problems, this utility model provides a cleaning and impurity removal device for onion processing.
[0004] To solve the above-mentioned technical problems, the present invention provides a cleaning and impurity removal device for onion processing, comprising a cleaning chamber, a support leg fixedly connected to the bottom of the cleaning chamber, an auger disposed inside the cleaning chamber, and several cleaning brushes disposed on both sides and below the auger. The cleaning brushes are rotatably connected to the cleaning chamber, and adjacent cleaning brushes on the same side are drive-connected. The main shaft of any cleaning brush on the left side is drive-connected to the output end of a third motor, and the main shaft of any cleaning brush on the right side is drive-connected to the output end of a second motor. The auger is driven by a first motor, and the first, second, and third motors are all connected to the cleaning chamber. The cleaning chamber is fixedly connected, and a filter plate is detachably connected to the lower part of the cleaning chamber. A water outlet is provided on one side of the bottom of the cleaning chamber, and the water outlet is connected to a water storage tank. A pump is fixedly connected to the water storage tank, and the water inlet pipe of the pump extends into the water storage tank. A spray pipe is fixedly connected to the output end of the pump. The spray pipe is fixed above the cleaning chamber by a bracket, and a spray head is fixedly connected to the bottom of the spray pipe. A discharge hopper is provided on one side of the cleaning chamber located at the output end of the auger. A rinsing tank is provided at the bottom of the discharge hopper. A chain plate elevator is inclinedly arranged in the rinsing tank, and a transmission belt is provided below the output end of the chain plate elevator.
[0005] Furthermore, the gap between adjacent cleaning brushes is no greater than 5 cm.
[0006] Furthermore, a cleaning port is provided on one side of the cleaning chamber, and the position of the cleaning port corresponds to the position of the filter plate.
[0007] Furthermore, the bottom of the cleaning chamber is inclined, with the lower end facing the water outlet.
[0008] This utility model has the following advantages compared with the prior art:
[0009] This invention utilizes sprayed water and rotating cleaning brushes to clean and remove the mud and skin from onions. The cleaned onion skins, dirt, stones, and other impurities fall through the gaps between the cleaning brushes onto a filter plate below. The cleaning water flows back to the water storage tank through the filter plate and is then pumped back to the spray pipes for reuse, ensuring cleaning effectiveness while conserving water resources. While being cleaned, the onions are transported to a rinsing tank by a slowly rotating auger for rinsing, and finally retrieved by a chain conveyor and transported to the next processing stage by a conveyor belt.

[0014] The present invention will be further described below with reference to the accompanying drawings.
[0015] like Figures 1 to 3The illustrated onion processing cleaning and impurity removal device includes a cleaning chamber 1, with a support leg 14 fixedly connected to the bottom of the cleaning chamber 1. An auger 2 is installed inside the cleaning chamber 1. The auger 2 has a shell-less structure. Several cleaning brushes 3 are arranged around the auger 2 on both sides and below it. The cleaning brushes 3 serve both to support and clean the onions. The cleaning brushes 3 are rotatably connected to the cleaning chamber 1. Adjacent cleaning brushes 3 on the same side are connected via a belt or sprocket chain. The main shaft of any cleaning brush 3 on the left side is connected to the output end of a third motor 7, and the main shaft of any cleaning brush 3 on the right side is connected to the output end of a second motor 6. The auger 2 is driven by a first motor 5. The first motor 5, second motor 6, and third motor 7 are all fixedly connected to the cleaning chamber 1. The lower part of the washing chamber 1 is detachably connected to a filter plate 4 via buckles, grooves, etc., which facilitates the periodic removal and cleaning of the filter plate 4. A water outlet is provided on one side of the bottom of the washing chamber 1, which is connected to a water storage tank 8. A pump 9 is fixedly connected to the water storage tank 8. The water supply pipe 10 of the pump 9 extends into the water storage tank 8. A spray pipe 11 is fixedly connected to the output end of the pump 9. The spray pipe 11 is fixed above the washing chamber 1 by a bracket. Several spray heads 12 are fixedly connected to the bottom of the spray pipe 11. A discharge hopper 13 is provided on one side of the washing chamber 1 at the output end of the auger 2. A rinsing tank 15 is provided at the bottom of the discharge hopper 13. A chain plate elevator 16 is inclinedly installed in the rinsing tank 15 to retrieve the onions from the rinsing tank 15. A transmission belt 17 is provided below the output end of the chain plate elevator 16.
[0016] To ensure that onions do not leak to the bottom of the cleaning chamber 1 while allowing impurities such as onion skins, dirt, and stones to fall through, the gap between adjacent cleaning brushes 3 shall not exceed 5cm.
[0017] To facilitate the removal and cleaning of filter plate 4, a cleaning port is provided on one side of the cleaning chamber 1, and the position of the cleaning port corresponds to the position of filter plate 4.
[0018] To prevent sediment from accumulating at the bottom of the cleaning chamber 1, the bottom of the cleaning chamber 1 is tilted, with the lower end facing the water outlet, so that sediment and other impurities can flow into the water storage tank 8 with the water flow.
[0019] The working process of this embodiment is as follows:
[0020] During operation, onions are added to the cleaning chamber 1. The second motor 6 and the third motor 7 drive the cleaning brushes 3 on the same side to rotate, turning the onions and washing away the skin, dirt, and other impurities on the surface. The cleaning water sprayed from the spray pipe 11 carries the skin, dirt, and other impurities through the gaps between the cleaning brushes 3 into the bottom of the cleaning chamber 1. The skin and large particles of sand are filtered to the top of the filter plate 4, while the cleaning water passes through the filter plate 4 into the water storage tank 8 for recycling. To prevent the water in the water storage tank 8 from becoming too turbid and affecting the spraying effect, it also needs to be replaced regularly. After the adhesive impurities and onion skin on the surface of the onions are washed away, the slowly rotating auger 2 transports the onions from the cleaning chamber 1 to the rinsing tank 15 for rinsing. After rinsing, the chain plate elevator 16 lifts the onions and transports them to the conveyor belt 17. The rinsing tank 15 also needs to have its rinsing water replaced regularly to ensure the cleaning effect of the onions.
