Description

Technical Field

[0001] This application relates to the field of tea production equipment technology, specifically a tea leaf washing device. Background Technology

[0002] In tea processing, the initial processing of fresh leaves is a core step in quality control. After picking, fresh tea leaves are covered with natural contaminants such as dust, insect eggs, and bird droppings; agricultural residues such as pesticides and foliar fertilizer particles; and their own secretions such as tea hair lipids and sugary mucus. Traditional processing relies on manual washing, but this method suffers from low efficiency and high breakage rates. With the development of large-scale planting, continuous washing equipment has become a necessity for industrial upgrading.

[0003] The existing patent with publication number CN222535668U provides a high-efficiency cleaning device for tea processing, which includes a tea cleaning box, a tea conveying component, a first spraying component, and a second spraying component. The first and second spraying components spray water onto the tea leaves for rinsing, and the stirring paddle can stir and adjust the position of the tea leaves, which can avoid the situation where only the side of the tea leaves that is exposed is cleaned when one side is placed against the tea conveying component.

[0004] The aforementioned patent enhances the all-around cleaning effect of tea leaves. However, in actual use, a significant amount of moisture remains on the surface of the tea leaves after cleaning by the first and second spray components, resulting in a longer drying time and hindering work efficiency. Furthermore, the excessive moisture on the tea leaves makes them prone to adhering to the surface and crevices of the conveyor belt. This adhered tea leaves affect the cleanliness of the conveyor belt and cause some tea leaves to be washed repeatedly, increasing the breakage rate and leading to waste. Therefore, it is necessary to provide a fresh tea leaf cleaning device to address these issues.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] like Figure 1-4 As shown, this application provides a tea leaf washing device, including a washing water tank 1. The bottom of the washing water tank 1 is funnel-shaped, which facilitates the collection of sediment and is connected to a drain valve (not shown in the figure). A filter plate (not shown in the figure) is fixedly installed in the middle of the interior of the washing water tank 1. The filter plate divides the washing water tank 1 into upper and lower layers: the upper layer is the tea washing area, and the lower layer is the wastewater sedimentation area. The tea leaves are washed by water flow and air bubbles above the filter plate, while heavy impurities such as mud and sand sink to the bottom of the funnel through the filter plate mesh, avoiding secondary contact between the tea leaves and the sedimented impurities during the washing process.

[0021] A discharge rack 3 is fixed on one side of the water tank 1. The end of the discharge rack 3 is inclined upward and extends out of the washing water tank 1. The discharge rack 3 has an inclined section and an upper horizontal section. A chain plate conveyor belt 4 with the same path as the discharge rack 3 is installed inside the discharge rack 3. The chain plate conveyor belt 4 is driven by a motor. The chain plate of the chain plate conveyor belt 4 has mesh and multiple baffles are fixed at intervals on the surface to facilitate the conveying of tea leaves.

[0022] A circulating water supply assembly 2 for water supply is fixedly installed on one side of the bottom of the cleaning water tank 1. The circulating water supply assembly 2 includes a water pump 21. The outlet end of the water pump 21 is fixedly connected to a return water pipe 23. The end of the return water pipe 23 is installed on the side of the cleaning water tank 1 away from the discharge rack 3 and is fixedly provided with multiple nozzles 24 extending into the cleaning water tank 1. The inlet end of the water pump 21 is connected to a filter box 22. The filter box 22 is fixedly installed on one side of the cleaning water tank 1, and an opening for water flow is provided between its upper side and the cleaning water tank 1.

[0023] The filter box 22 is equipped with a filter structure, such as a filter screen, for filtering the returned liquid. The water pump 21 draws filtered water from the filter box 22 and sprays it into the cleaning water tank 1 at a certain pressure through the nozzle 24, forming a water flow. The nozzle 24 is angled towards the bottom of the chain conveyor belt 4, which pushes the tea leaves to tumble and surge towards the chain conveyor belt 4, thus serving as both a cleaning and conveying auxiliary function.

[0024] An air supply assembly 6 is fixedly installed on the other side below the cleaning water tank 1. The air supply assembly 6 includes an air pump 61. An air supply pipe 62 is fixedly connected to the air outlet of the air pump 61. Multiple aeration pipes 63 extending into the cleaning water tank 1 are fixedly connected to one side of the air supply pipe 62. The air pump 61 supplies air, and the bubbles generated by the aeration pipes 63 rise from the bottom of the cleaning water tank 1. The bubbles disturb the water flow, enhance the cleaning force, and fully disperse the tea leaves to ensure the cleaning effect.

[0025] A pre-draining component 5 is fixedly installed on the outside of the inclined section of the discharge rack 3. The pre-draining component 5 is used to pre-drain the tea leaves that have just been brought out of the inclined section, reduce the moisture carried by the tea leaves, improve the efficiency of subsequent air drying, and at the same time, reducing the moisture can also reduce the phenomenon of tea leaves sticking to the chain conveyor belt.

[0026] Specifically, the pre-draining component 5 includes mounting brackets 51 installed on both sides of the discharge rack 3. Multiple air distribution pipes 53 are fixedly connected between the mounting brackets 51. Air outlets 54 are fixedly connected to the lower side of each of the multiple air distribution pipes 53. The air outlets 54 are trumpet-shaped and have sufficient space between their lower ends and the chain conveyor belt 4 so as not to interfere with the baffles on the chain conveyor belt 4. The trumpet-shaped air outlets 54 can form an air curtain covering the width of the conveyor belt to gently blow away the freshly drained tea leaves.

[0027] In addition, the lower end of the air outlet 54 is parallel to the inclined section of the chain conveyor belt 4, and the inclined angle design ensures that the air force is concentrated on the surface of the tea leaves. The ends of multiple air distribution pipes 53 are connected to the second air supply pipe 52, and the end of the second air supply pipe 52 is connected to the first air supply pipe 62. The pre-drying component 5 is also supplied with air by the air pump 61, so no additional air supply equipment is required.

[0028] The horizontal section of the chain conveyor belt 4 is equipped with a cleaning component 9. The cleaning component 9 is used to clean the tea leaves adhering to the surface of the chain conveyor belt 4, reduce tea waste, and prevent some tea leaves from being over-washed.

[0029] Specifically, the cleaning component 9 includes an air outlet pipe 93 and a cleaning brush 94. Both ends of the air outlet pipe 93 are fixedly connected to the discharge rack 3, and one end is connected to an air supply pipe 91 that communicates with the second air supply pipe 62. Multiple air outlet heads inclined downwards towards the conveyor chain plate are provided on the lower side of the air outlet pipe 93. Both ends of the cleaning brush 94 are rotatably connected to the discharge rack 3, and the bristles of the cleaning brush 94 contact the lower conveyor chain plate. The bristles of the cleaning brush 94 are designed to extend beyond the mesh openings of the conveyor chain plate. When brushing, the bristles can brush off the adhering tea leaves and scrape away tea fragments embedded in the mesh, preventing residual fermentation from affecting the quality of subsequent batches. The air outlet pipe 93 sprays airflow into the mesh openings of the chain plate through the air outlet heads, blowing off the adhering tea leaves, forming a dual cleaning process with the cleaning brush to ensure thorough cleaning.

[0030] The cleaning assembly 9 also includes two meshing gears 92. One gear 92 is fixed to the shaft end of the cleaning brush 94, and the other gear 92 is fixedly connected to the shaft end of the end roller of the chain conveyor belt 4. The end roller of the chain conveyor belt 4 drives the cleaning brush 94 to rotate in the opposite direction through the gear set, without the need for additional power.

[0031] The lower end face of the horizontal section of the discharge rack 3 is provided with an opening 7. A downwardly inclined guide plate 8 is fixedly connected to one side of the opening 7. A collection device (not shown in the figure), such as a wire mesh frame, can be set below the opening 7. The tea leaves cleaned by the cleaning component 9 can fall into the collection device for subsequent centralized processing, reducing tea waste.

[0032] Working principle: When in use, clean water is poured into the cleaning water tank 1, and fresh tea leaves are put into the cleaning water tank 1. The water pump 21 pressurizes the water through the nozzle 24 and sprays it out, forming a directional water flow that pushes the tea leaves to roll and move towards the chain conveyor belt 4. At the same time, the air pump 61 injects air bubbles into the bottom of the water tank through the aeration pipe 63, disturbing the water flow and making the tea leaves fully dispersed.

[0033] After the tea leaves have been washed, they are lifted out of the water by the chain conveyor belt 4. In the inclined section, the trumpet-shaped air outlet 54 of the pre-draining component 5 sprays an air curtain parallel to the conveyor belt to gently sweep the surface of the tea leaves, reducing the surface moisture and adhesion. The mesh structure of the chain conveyor belt 4 facilitates drainage, and the baffles on the surface prevent the tea leaves from slipping, thus smoothly conveying them to the upper horizontal section.

[0034] After the tea leaves fall off the horizontal section of the chain conveyor belt 4, they enter the next station. The tea leaves that do not fall off are blown off by the airflow sprayed by the rotating cleaning brush 94 and the air outlet 93. The removed tea leaves are discharged through the outlet 7 for subsequent centralized processing.

[0035] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
