Description

Technical Field

[0001] This invention relates to the field of mesh chain cleaning equipment technology, specifically to mesh chain cleaning equipment for onion processing. Background Technology

[0002] Currently, in the deep processing of onions, surface cleaning of raw onions is one of the core steps in the pre-processing stage, directly affecting the quality of finished products in subsequent processing steps such as slicing, dehydration, and seasoning. At present, large-scale production often adopts mesh conveyor cleaning equipment, which uses a mesh belt to continuously transport onions and uses an overhead spray structure to wash away surface mud and impurities, thereby achieving continuous operation.

[0003] However, existing mesh chain onion washing equipment still has several technical defects in actual use:

[0004] Firstly, the circulating filtration structure of the cleaning water is rudimentary, often using single or double-layer flat filter plates for simple filtration. This fails to effectively intercept impurities of different particle sizes, such as silt and outer skin debris, resulting in insufficient filtration precision and limited cleanliness of the circulating water. After long-term circulation, the water quality easily becomes turbid and the cleaning effect declines. At the same time, impurities easily accumulate on the surface of the filter plates, causing filter pore blockage. Frequent shutdowns for manual cleaning are required, which seriously affects the continuous operation efficiency of the production line.

[0005] Secondly, the onions are in a fixed position during the conveyor belt process, and the spray water can only wash the top surface of the onions. The mud and sand at the bottom of the onions and in the crevices are difficult to clean effectively, resulting in poor cleaning uniformity. Some equipment with fixed turning baffles has a fixed turning angle that cannot be adjusted, making it unsuitable for onions of different sizes. Large-diameter onions are prone to jamming and damage from impacts, while small-diameter onions have insufficient turning range, resulting in limited cleaning and lifting effects and poor equipment applicability.

[0006] Third, the equipment lacks a real-time monitoring mechanism for filter blockage. The degree of blockage of the filter plates can only be judged by manual periodic inspections, making it difficult to detect filter hole blockage problems in a timely manner. This can easily lead to malfunctions such as reduced water circulation flow and insufficient spray pressure. In severe cases, it can even cause the circulation pump to run dry and be damaged. The equipment has high maintenance costs and insufficient fault early warning capabilities. Summary of the Invention

[0013] Preferably, a permeation filter frame is installed at the top of the inner cavity of the guide frame, a working coupling is installed in the middle of the inner cavity of the permeation filter frame, and the bottom end of the connecting rod is connected to the top end of the working coupling. A turbine fan head is installed at the bottom end of the working coupling via a movable rod. A working brush strip is provided at the top of the permeation filter frame, and the working brush strip is connected to the bottom end of the connecting rod. The bottom end of the connecting rod is connected to the top end of the working coupling.

[0014] Preferably, a movable hole is provided at the upper middle end of one side of the collection hopper frame, and a monitoring bend is installed on the right side of the inner cavity of the collection hopper frame at the corresponding position of the movable hole, with the end of the monitoring bend away from the movable hole facing downwards.

[0015] Preferably, a monitoring frame head is installed on the right side of the collection hopper frame at the corresponding position of the movable hole.

[0017] Preferably, movable slide rails are installed at the bottom center of both sides of the inner cavity of the working frame, and movable sleeves are slidably installed on the upper outer side of the movable slide rails. The end of the mounting shaft away from the tumbling shovel is connected to one side of the movable sleeve.

Bearings are installed on one side of the mounting shaft.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention forms a three-stage filtration structure by collecting the first filter plate, the second filter plate, and the permeation filter frame within the collection bucket frame. The pore size of the filter holes decreases progressively, which can sequentially intercept impurities such as onion peels and silt of different particle sizes in the wastewater, achieving graded filtration and significantly improving the filtration accuracy and cleanliness of the circulating water, ensuring the cleaning effect of the spray cleaning. At the same time, through the working motor, magnetic coupling, and working coupling, the arc-shaped brush strip and the working brush strip are synchronously driven to rotate on the surface of the filter plate, which can scrape off the impurities accumulated on the surface of the filter plate in real time, effectively avoiding filter hole clogging, eliminating the need for frequent shutdowns to clean the filter plates, and improving the stability of continuous production of the equipment. In addition, the linked-drive turbine head can create a negative pressure water delivery effect in the guide frame, enhance the delivery power of the circulating water, ensure the stability of the water pressure in the spray pipeline, improve the water resource recycling rate, and reduce the processing water consumption.

[0020] 2. This invention features an adjustable tumbling shovel plate above the washing mesh chain. As the onions are conveyed along the mesh chain, they move along the inclined surface of the shovel plate and tumble naturally, ensuring that all sides of the onion are fully in contact with the sprayed water, thoroughly cleaning the mud and sand impurities at the bottom and in the crevices of the onion's skin, significantly improving the uniformity and cleanliness of the cleaning. At the same time, a small electric push rod can drive the tumbling shovel plate to rise and fall along the moving slide rail, flexibly changing the tilt angle and lifting height of the shovel plate, which can adapt to onion raw materials of different sizes and specifications. This avoids large-diameter onions getting stuck and bumped, while ensuring that small-diameter onions get sufficient tumbling range, thus broadening the range of raw materials applicable to the equipment. Furthermore, the matching structure of the slide rail and sliding sleeve improves the operational stability of the adjustment process, making the equipment reliable in operation.

[0021] 3. This invention features a monitoring mechanism consisting of a monitoring bend, an expansion bladder, and a pressure controller. When the filter plate becomes clogged, causing the liquid level in the collection hopper to rise, water will enter the monitoring bend and trigger the expansion bladder to expand. This, in turn, triggers the pressure controller to issue an early warning signal via the squeezing plate. This allows for real-time monitoring of the filter plate's clogging status, eliminating the need for frequent manual inspections. It can promptly remind staff to clean and maintain the filter in the early stages of clogging, preventing problems such as poor water circulation, insufficient spray pressure, or even equipment damage caused by clogging. This reduces the difficulty of equipment operation and maintenance and the risk of failure, thereby improving the reliability of the production line. Attached Figure Description

A cleaning spray pipe rack 5 is installed at the upper end of the inner cavity of the working frame 2. Several spray nozzles are installed at equal intervals at the bottom of the cleaning spray pipe rack 5.

[0031] The tumbling mechanism 6 is installed at the bottom of the middle part of the inner cavity of the working frame 2. The bottom of the inner cavity of the working frame 2 is equipped with a circulation processing mechanism 7, and a monitoring mechanism 8 is installed inside the circulation processing mechanism 7.

[0032] A collection bucket frame 701 is installed at the top of the inner cavity of the working frame 1 at the bottom of the cleaning net chain 4. The collection bucket frame 701 has an inverted bucket shape. A guide frame 707 is installed at the bottom of the collection bucket frame 701. A conveying pipe 710 is installed at the bottom of the guide frame 707. A connecting pipe head is installed at the corresponding position of the cleaning spray pipe frame 5 on the upper left side of the working frame 2. The end of the conveying pipe 710 away from the guide frame 707 is connected to the bottom of the connecting pipe head.

[0033] A working motor 702 is installed in the middle of the inner cavity of the working frame 1. A working rotating rod 703 is installed at the bottom of the working motor 702. A second filter plate 705 is installed at the bottom of the inner cavity of the collecting hopper frame 701. A first filter plate 704 is installed in the middle of the inner cavity of the collecting hopper frame 701. Both the first filter plate 704 and the second filter plate 705 have an arc-shaped structure. Magnetic couplings are installed in the middle of both the first filter plate 704 and the second filter plate 705. The bottom end of the working rotating rod 703 is connected to the magnetic coupling at the top end. A connecting rod is installed between the magnetic couplings at the top and bottom ends. A connecting rotating rod is installed at the bottom end of the magnetic coupling at the bottom end. Both the first filter plate 704 and the second filter plate 705 have an arc-shaped structure. Arc-shaped brush strips 706 are provided at the top of both the first filter plate 704 and the second filter plate 705. The middle of the arc-shaped brush strips 706 is connected to the working rotating rod 703 and the connecting rod.

[0034] A permeation filter frame 708 is installed at the top of the inner cavity of the guide frame 707. A working coupling is installed in the middle of the inner cavity of the permeation filter frame 708. The bottom end of the connecting rod is connected to the top end of the working coupling. A turbine fan head 709 is installed at the bottom end of the working coupling through a movable rod. A working brush strip 711 is provided at the top of the permeation filter frame 708. The working brush strip 711 is connected to the bottom end of the connecting rod. The bottom end of the connecting rod is connected to the top end of the working coupling. A control panel is installed at the top of one side of the working frame 1. The working motor 702 is electrically connected to the control panel. The filter holes of the first filter plate 704 are larger than the filter holes of the second filter plate 705. The permeation filter frame 708 and its filter holes are smaller than the filter holes of the second filter plate 705.

[0035] The specific implementation method is as follows: when the liquid is sprayed onto the outside of the onion at the top of the cleaning net chain 4 through the cleaning spray pipe frame 5 for cleaning, the cleaned liquid will flow into the collection hopper frame 701 and filter impurities of different sizes in the collected liquid through the first filter plate 704 and the second filter plate 705 inside the collection hopper frame 701. After the initial filtration is completed, the liquid is filtered through the permeation filter frame 708 to filter even finer impurities. Through filtration of different sizes at different positions, multi-stage impurity treatment is achieved, increasing the efficiency of liquid reuse.

[0036] Simultaneously, the working motor 702, magnetic coupling, and working coupling are started. The working motor 702 and the magnetic couplings at different positions drive the working rotating rod 703, connecting rod, connecting rotating rod, and movable rod to rotate. This, in turn, drives the turbine head 709 to rotate at the bottom of the guide frame 707's inner cavity. A negative pressure state is created at the top of the guide frame 707's inner cavity, simultaneously conveying the multi-stage filtered liquid into the delivery pipe 710, and then through the connecting pipe head to the cleaning spray pipe rack 5. Finally, the liquid is sprayed through the cleaning spray... The head sprays liquid to clean the outside of the onion. This process is repeated in a cycle. While cleaning the onion, the liquid water after cleaning can also be recycled. At the same time, the working rotating rod 703, connecting rod and connecting rotating rod drive the arc-shaped brush 706 and working brush 711 to rotate. The arc-shaped brush 706 and working brush 711 then sweep the top of the first filter plate 704, the second filter plate 705 and the permeate filter frame 708 respectively, so as to avoid too much impurities accumulating at the top of the filter end and affecting the subsequent filtration operation.

[0037] An movable hole is provided at the upper middle end of one side of the collection bucket frame 701, and a monitoring bend 801 is installed on the right side of the inner cavity of the collection bucket frame 701 at the corresponding position of the movable hole. The end of the monitoring bend 801 away from the movable hole faces downward.

[0038] A monitoring frame head 802 is installed on the right side of the collection hopper frame 701 at the corresponding position of the movable hole. An inflatable air bladder 803 in a contracted state is installed at the top of the inner cavity of the monitoring frame head 802. A compression plate 804 is installed at the bottom of the inflatable air bladder 803. A pressure controller 805 is installed at the bottom of the inner cavity of the monitoring frame head 802. The pressure controller 805 is electrically connected to the control panel.

[0039] The specific implementation method is as follows: When too many impurities accumulate at the top of the first filter plate 704 or the second filter plate 705, affecting the normal flow of liquid water, they will accumulate inside the collection hopper frame 701. When too much liquid is collected inside the collection hopper frame 701, the liquid will flow into the monitoring bend 801, and finally into the expansion bladder 803, causing the expansion bladder 803 to expand and drive the squeezing plate 804 to move downward, so that the bottom end of the squeezing plate 804 contacts the top end of the pressure controller 805. When squeezing the pressure controller 805, the pressure value is fed back to the control panel to issue an alarm, informing the staff that the inside of the collection hopper frame 701 needs to be treated to avoid excessive accumulation of impurities affecting subsequent cleaning operations.

[0040] The bottom of the inner cavity of the working frame 2 is provided with a tumbling shovel plate 601. The top of both sides of the tumbling shovel plate 601 are provided with mounting shafts 605. The top of the tumbling shovel plate 601 is provided with a conveying inclined surface 606. The bottom front side of the tumbling shovel plate 601 is in contact with the top of the cleaning mesh chain 4.

[0041] Movable slide rails 604 are installed at the bottom center of both sides of the inner cavity of the working frame 2. Movable sleeves 603 are slidably installed on the upper outer side of the movable slide rails 604. The end of the mounting shaft 605 away from the tumbling shovel plate 601 is connected to one side of the movable sleeve 603. A small electric push rod 602 is installed on the right side of the inner cavity of the working frame 2, and the bottom end of the small electric push rod 602 is connected to the top end of the mounting shaft 605 on the right side. Bearings are installed on one side of the mounting shaft 605.

[0042] The specific implementation method is as follows: During the onion conveying and cleaning process by the cleaning mesh chain 4, the pushing force generated by the cleaning mesh chain 4 causes the onion to move at the top of the tumbling shovel 601. When the onion moves past the top of the tumbling shovel 601, it will tumble. When the onion tumbles, it can be cleaned more thoroughly. When the size of the onion is too large and the overall tilt angle of the tumbling shovel 601 needs to be adjusted, the small electric push rod 602 is activated to drive the right mounting shaft 605 to move downward, which in turn drives the rear side of the tumbling shovel 601 to move downward. During the downward movement of the mounting shaft 605, the moving sleeve 603 slides outside the moving slide rail 604, which improves the stability and flexibility of the tumbling shovel 601 during movement adjustment. It can be adjusted according to different sizes, increasing its applicability in the cleaning process.
