Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wood ear cleaning technology, and in particular relates to a high-frequency vibration wood ear mud and sand cleaning and impurity removal machine. Background Technology
[0002] As an important edible fungus, wood ear mushrooms have fruiting bodies rich in colloids and complex folded structures on their surface. During natural growth and harvesting, they easily absorb mud, microorganisms, and organic impurities. Wood ear mushrooms can be wild or artificially cultivated. Artificial cultivation mainly uses sawdust, rice straw, cow dung, etc. as growth substrates and nutrients. Since the root of the wood ear mushroom will stick to the planting soil, sawdust, straw, and bran planting culture medium, it is necessary to thoroughly remove the mud and sand attached to the folds and surface impurities during the processing.
[0003] Traditional cleaning processes rely on manual rubbing or simple mechanical equipment, which suffers from low efficiency, high damage rate, and serious water waste. Currently, there are also technologies that use machines for cleaning. For example, the authorized announcement number CN222692694U discloses a black fungus processing and cleaning device. During operation, the first motor drives the arc plate to rotate, which causes the arc plate to scoop up the black fungus to be cleaned and turn it over for cleaning. The arc plate has a large area and a mesh structure, which increases the contact area between the black fungus and the arc plate and reduces the resistance of the arc plate's rotation, thus allowing for a larger and more comprehensive turning of the black fungus.
[0004] In the above solution, stirring is used to improve the cleaning effect of wood ear fungus. However, wood ear fungus is soft and has many folds and pores on its surface. During mechanical stirring, the rotation of the arc plate will generate direct mechanical force and friction on the wood ear fungus. This mechanical force can easily damage the structure of the wood ear fungus, making it soft, mushy and broken, which seriously affects the appearance and quality of the wood ear fungus.
[0005] To address this issue, we propose a high-frequency vibration-type wood ear mushroom cleaning and impurity removal machine. Utility Model Content
[0006] The purpose of this invention is to solve the problem that mechanical stirring and cleaning in the prior art causes significant damage to wood ear mushrooms, and to propose a high-frequency vibration wood ear mushroom mud and sand cleaning and impurity removal machine.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A high-frequency vibration type wood ear mushroom cleaning and impurity removal machine includes:
[0009] The cleaning tank has an overflow port on the upper part of its side wall, and the bottom surface of the overflow port is flush with the normal working liquid level in the cleaning tank.
[0010] The material conveying assembly includes a conveyor belt and a pressing conveyor belt. A channel for the fungus to pass through is formed between the conveyor belt and the pressing conveyor belt. Multiple mesh holes are evenly distributed on the pressing conveyor belt, and the liquid level in the washing tank is located in the middle of the pressing conveyor belt.
[0011] A bubble generating system includes a bubble generating tube and a high-pressure air pump. The surface of the bubble generating tube is provided with a micropore array and is connected to the high-pressure air pump through an air supply pipeline. The air supply pipeline is also connected to a transverse air blowing pipe corresponding to the overflow port position.
[0012] A water circulation system is used to recycle the cleaning water in the cleaning tank.
[0013] Preferably, the bottom of the cleaning pool is provided with a trapezoidal sedimentation tank.
[0014] Preferably, the mesh diameter of the pressing conveyor belt is 3-8 mm.
[0015] Preferably, the outer surfaces of the conveyor belt and the pressing conveyor belt are each provided with multiple partitions at equal intervals, and the partitions are arranged along the width direction of the washing pool.
[0016] Preferably, the conveyor belt has a low-level conveying section, a lifting section, and a high-level conveying section, and one side of the input end of the downward-pressing conveyor belt is an inclined surface.
[0017] Preferably, the water circulation system includes a filter tank connected to the cleaning tank through an overflow outlet, a filter screen is installed in the filter tank, and a return pump is connected to the output end of the filter tank and connected to the spray pipe through the return pump.
[0018] The spray pipe is positioned above the lifting section of the conveyor belt, and the spray pipe is equipped with nozzles whose spray direction forms a 45-60° angle with the normal of the conveyor surface of the lifting section.
[0019] Preferably, the nozzle is a fan-shaped nozzle, and the spray angle of the nozzle is 60-90°.
[0020] In summary, the technical effects and advantages of this utility model are as follows:
[0021] This device uses high-frequency vibration of air bubbles in a cleaning tank to clean wood ear mushrooms. This non-mechanical contact cleaning method can penetrate deep into the folds and pores of the wood ear mushrooms, effectively removing impurities and dirt attached to them, greatly improving the cleaning effect. At the same time, by avoiding direct contact between mechanical parts and wood ear mushrooms in traditional mechanical stirring methods, it significantly reduces damage to the wood ear mushrooms caused by mechanical friction and collision, ensuring the integrity and quality of the wood ear mushrooms, which is beneficial for subsequent processing and sales.
[0022] Considering that the density of wood ear mushrooms is close to that of water, some wood ear mushrooms may float on the surface. This device uses a combination of a pressure conveyor belt and a conveyor belt. The pressure conveyor belt can force the wood ear mushrooms to stay submerged in the water in the washing tank, ensuring that all the wood ear mushrooms are fully immersed in the washing solution. This avoids the problem of some wood ear mushrooms not being thoroughly cleaned due to floating, thereby improving the uniformity and comprehensiveness of the overall washing effect.
[0023] The mesh on the conveyor belt allows lightweight impurities, such as sawdust, to float to the surface of the water and be collected at the overflow port by air blown through the mesh. The impurities are then easily removed in the filtration tank. The water after washing is then filtered and purified and recycled, which greatly reduces water consumption, conforms to the concept of environmental protection and energy conservation, and also reduces production costs.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0030] Reference Figure 1-4 A high-frequency vibration type wood ear mushroom cleaning and impurity removal machine includes a cleaning tank 1, a material conveying component, a bubble generating system and a water circulation system.
[0031] The wood ear mushrooms are placed into the washing tank 1 and then transported directionally within the tank by a material conveying assembly, which includes a conveyor belt 2 and a pressing conveyor belt 3. A channel for the wood ear mushrooms to pass through is formed between the conveyor belt 2 and the pressing conveyor belt 3. The water level in the washing tank 1 is set to submerge the lower contact surface of the pressing conveyor belt 3. As the wood ear mushrooms enter the washing tank 1, they are conveyed into the channel by the conveyor belt 2. Some wood ear mushrooms with low water content will float on the water surface, resulting in poor washing effect. The pressing conveyor belt 3 forces the floating wood ear mushrooms into the channel, ensuring that the wood ear mushrooms are fully immersed in the washing solution and avoiding the problem of some wood ear mushrooms not being thoroughly cleaned due to floating.
[0032] Reference Figure 1-4 The conveyor belt 2 has a low-level conveying section 21, a lifting section 22, and a high-level conveying section 23. The low-level conveying section 21 is located below the water surface, and the high-level conveying section 23 is located above the water surface. The lifting section 22 is used for the transition between the low-level conveying section 21 and the high-level conveying section 23, lifting the cleaned wood ear mushrooms from the cleaning pool 1 to the high-level conveying section 23 and conveying them to the downstream equipment. The input end of the downpress conveyor belt 3 has an inclined surface on one side, and the inclined surface has an angle with the water surface, so that the wood ear mushrooms can gradually transition into the channel under the action of the downpress conveyor belt 3.
[0033] Both the conveyor belt 2 and the pressing conveyor belt 3 are existing technologies. The sprockets, shafts, chains, and drive motors involved are shown in the attached drawings and will not be described in detail here. In this embodiment, the conveyor belt 2 is a plate chain conveyor belt. The gaps between the plate chains provide support for the wood ear fungus and allow the bubble generation system to generate bubbles that act on the water in the channel. Heavy impurities such as gravel generated during the cleaning of the wood ear fungus are agitated by the water flow and partially deposited through the gaps between the plate chains. The pressing conveyor belt 3 is a belt conveyor belt with multiple mesh holes 31 evenly distributed on it. The liquid level in the cleaning pool 1 is located in the middle of the pressing conveyor belt 3. The diameter of the mesh holes 31 of the pressing conveyor belt 3 is 3-8mm. The wood ear fungus mesh holes 31 can block the wood ear fungus. Light impurities such as sawdust generated during the cleaning of the wood ear fungus continue to float to the surface through the mesh holes 31, achieving separation from the wood ear fungus material. After the impurities are separated, when the wood ear fungus is lifted off the water surface by the lifting part 22, it can effectively reduce the adhesion of the separated impurities to the surface of the wood ear fungus due to the residual water on the surface of the wood ear fungus.
[0034] Reference Figure 1-4 Multiple baffles 24 are evenly distributed on the outer surfaces of the conveyor belt 2 and the pressing conveyor belt 3. The baffles 24 are set along the width direction of the washing pool 1. The baffles 24 can effectively transport the wood ear fungus, which effectively solves the problem of low conveying efficiency caused by insufficient friction between the wood ear fungus and the conveyor belt 2 and the pressing conveyor belt 3.
[0035] The bubble generating system includes a bubble generating tube 4 and a high-pressure air pump 5. The bubble generating tube 4 is located below the upper contact surface of the conveyor belt 2 (below the upper conveyor belt). The surface of the bubble generating tube 4 is provided with a micropore array 41 and is connected to the high-pressure air pump 5 through an air supply pipe 51. The high-pressure air pump 5 generates high-pressure gas, which is transported to the bubble generating tube 4 through the air supply pipe 51. Bubbles are generated in the washing water through the micropore array 41. The vibration of the bubbles and the turbulence of the washing water are used to efficiently clean the wood ear fungus. This non-mechanical contact cleaning method can penetrate deep into the folds and pores of the wood ear fungus, effectively removing impurities and dirt attached to its deep layers, greatly improving the cleaning effect. At the same time, since it avoids the direct contact between mechanical parts and wood ear fungus in the traditional mechanical stirring method, it significantly reduces the damage to the wood ear fungus caused by mechanical friction and collision, ensuring the integrity and quality of the wood ear fungus.
[0036] Reference Figure 1-4 An overflow port 12 is provided on the upper part of the side wall of the cleaning tank 1. The bottom surface of the overflow port 12 is flush with the normal working liquid level in the cleaning tank 1. The air supply pipe 51 is also connected to a horizontal air blowing pipe 6 corresponding to the position of the overflow port 12. Air can be blown from the end of the cleaning tank 1 away from the overflow port 12 to the overflow port 12 through the horizontal air blowing pipe 6, blowing the impurities floating on the water surface into the overflow port 12 for collection. The bottom of the cleaning tank 1 is provided with a trapezoidal sedimentation tank 11. The trapezoidal sedimentation tank 11 is conducive to the gravity sedimentation of sediment. In addition, since the sedimentation tank 11 is located below the bubble generating pipe 4, the bubble generating pipe 4 generates bubbles upward, so the disturbance to the sedimentation tank 11 is small, reducing the risk of secondary disturbance of sediment. A slag discharge pipe is installed below the sedimentation tank 11 for periodic cleaning of sediment.
[0037] As a further improvement, a water circulation system is used to recycle the cleaning water in the cleaning tank 1. The water can be filtered and purified after cleaning and then recycled, which greatly reduces the consumption of water resources.
[0038] Reference Figure 1-4 The water circulation system includes a filter tank 7 connected to the cleaning tank 1 via an overflow port 12. Water entering the filter tank 7 through the overflow port 12 carries floating impurities. A filter screen 71 is installed inside the filter tank 7 to remove these impurities. A return pump 8 is connected to the output end of the filter tank 7, providing power for water circulation. A membrane filter can be installed on the output pipe of the filter tank 7 to remove suspended silt and other fine impurities, improving water quality. The output end of the return pump 8 is connected to a spray pipe 9, which sprays and washes the wood ear mushrooms, reducing residual impurities on the surface and improving the cleaning effect. (Depending on the actual situation, if the circulating water is too dirty, the return pump 8 should be turned off, the dirty water in the filter tank 7 should be drained, and a clean water source should be connected. Alternatively, the spray pipe 9 can be directly connected to a pressurized clean water source without circulating water.)
[0039] The spray pipe 9 is set above the lifting part 22 of the conveyor belt 2. The spray pipe 9 is equipped with nozzles 91 whose spray direction is at an angle of 45-60° to the normal of the conveying surface of the lifting part 22. The spray pipe 9 cleans the impurities in the residual moisture on the surface of the wood ear fungus by spraying and the spray water flows into the cleaning pool 1.
[0040] Nozzle 91 is a fan-shaped nozzle with a spray angle of 60-90°. The spray range of nozzle 91 partially overlaps, achieving comprehensive cleaning of the wood ear mushrooms.
[0041] The working principle of this utility model is as follows:
[0042] In use, the wood ear mushrooms are placed into the washing tank 1 and conveyed into the channel by the conveyor belt 2. The downward conveyor belt 3 forces the floating wood ear mushrooms into the channel, ensuring that they are fully immersed in the water and that all the wood ear mushrooms are fully soaked in the washing solution. High-pressure gas is generated by the high-pressure air pump 5 and delivered to the bubble generating pipe 4 through the air supply pipe 51. Bubbles are generated in the washing water through the microporous array 41. The vibration of the bubbles and the turbulence of the washing water are used to efficiently clean the wood ear mushrooms. Heavy impurities such as gravel generated during the washing of the wood ear mushrooms are agitated by the water flow and some of them are deposited through the gaps between the plates. Light impurities such as sawdust generated during the washing of the wood ear mushrooms continue to float to the surface through the mesh 31, achieving separation from the wood ear mushroom material. Air is blown from the end of the washing tank 1 away from the overflow port 12 through the horizontal air blowing pipe 6 to the overflow port 12, blowing the impurities floating on the water surface into the overflow port 12 for collection. The water entering the filtration tank 7 through the overflow port 12 carries the floating impurities and is filtered out by the filter screen 71.
[0043] After the impurities are separated, the wood ear mushrooms are sprayed and washed through the spray pipe 9 as they are lifted off the water surface by the lifting unit 22. This reduces the residual impurities on the surface of the wood ear mushrooms and improves the cleaning effect. The cleaned wood ear mushrooms are then lifted from the cleaning tank 1 to the high-level conveying unit 23 and transported to the downstream equipment.
