Description

Technical Field

[0001] This invention belongs to the technical field of tea processing equipment, and more specifically, relates to an integrated machine for water washing and dehydration treatment. Background Technology

[0002] In traditional tea processing, cleaning and drying require multiple steps. During the transition between cleaning and drying, tea leaves are prone to secondary contamination from contact with equipment or external sources, resulting in low efficiency and the risk of secondary contamination. Existing equipment is unable to achieve continuous suspension cleaning and rapid dehydration of tea leaves. Therefore, there is a need for an integrated water washing and air shower dehydration treatment machine that can continuously perform suspension cleaning to improve the cleaning efficiency of tea leaves and achieve rapid dehydration. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an integrated water washing and dehydration treatment machine that can meet the needs of continuous suspension cleaning and rapid dehydration of tea leaves.

[0004] This invention discloses an integrated washing and dehydration treatment machine, comprising a washing mechanism, a dehydration mechanism, a conveying channel, a high-pressure atomizing washing channel, and a water pump. The two ends of the conveying channel are respectively connected to the tail end of the washing mechanism and the feed end of the dehydration mechanism, enabling the conveying of tea leaves from the washing mechanism to the dehydration mechanism. The high-pressure atomizing washing channel is connected to the water pump via a pipe. The washing mechanism includes a conveyor belt and a protective cover fixedly fastened to the conveyor belt. The high-pressure atomizing washing channel is formed by setting a high-pressure atomized water vapor impact direction, causing it to act on the conveyor belt to create a suspended movement channel for the tea leaves. Under the impact direction of the high-pressure atomized water vapor, the tea leaves... The conveyor belt suspends and tumbles forward towards the exit. The high-pressure atomized water washing channel can be achieved by selecting several high-pressure atomized water guns with multiple spray angles or several high-pressure atomized spray heads. Several high-pressure atomized water guns or high-pressure atomized spray heads are fixedly installed on the inner side of the water washing mechanism, on the inner wall above the protective cover, or below the conveyor belt. The dehydration mechanism has a drying fan fixedly installed at the bottom near the water washing mechanism. The tail end of the dehydration mechanism has an upward-sloping arc-shaped pipe. The air blown by the drying fan is inclined upward along the pipe, which can blow the tea leaves conveyed to the dehydration mechanism upward and make the tea leaves fall freely on the other side and be conveyed out of the dehydration mechanism.

[0005] As a further improvement of the present invention, a plurality of high-pressure atomizing water guns are provided. The left side of the protective cover along the conveyor belt conveying direction is designated as the first side and the right side as the second side. The lower ends of both sides of the protective cover are flat and the upper ends are arc-shaped. The plurality of high-pressure atomizing water guns are arranged in four groups and fixedly installed on the flat inner wall and arc-shaped inner wall of the first side and the flat inner wall and arc-shaped inner wall of the second side, respectively. Each group of high-pressure atomizing water guns is arranged horizontally. The spray nozzles of the plurality of high-pressure atomizing water guns fixedly installed on the first side and the second side all face the conveying end point. The spray nozzles of the plurality of high-pressure atomizing water guns fixedly installed on the flat inner wall are all offset upward. The spray nozzles of the plurality of high-pressure atomizing water guns fixedly installed on the arc-shaped inner wall are all offset downward.

[0006] As a further improvement of the present invention, the arc-shaped inner wall of the first side and the planar inner wall of the second side are arranged opposite each other in the vertical direction, and the planar inner wall of the first side and the arc-shaped inner wall of the second side are arranged opposite each other in the vertical direction, so that the spray nozzles offset upward and the spray nozzles offset downward are continuously alternately arranged along the conveying direction.

[0007] As a further improvement of the present invention, the water loss mechanism is provided with a mesh surface around its perimeter and top surface, so that the air from the drying fan is dispersed from the mesh surface, thus avoiding the formation of turbulence.

[0008] As a further improvement of the present invention, a wastewater tank is fixedly installed below the water washing mechanism to store water droplets falling from the high-pressure atomized water washing channel when rinsing the tea leaves, so as to prevent water droplets with dirt and dust from being conveyed out of the water washing mechanism with the tea leaves and affecting the rinsing and cleaning efficiency.

[0009] As a further improvement of the present invention, the conveyor belt is configured as a mesh or chain drive, wherein the mesh opening size is no larger than the size of the tea leaves, so that water droplets can leak from the mesh into the wastewater tank for storage while preventing tea leaves from falling into the wastewater tank with the mesh.

[0010] As a further improvement of the present invention, a conveying fan is fixedly installed on the bottom side of the conveying channel, and the blowing direction of the conveying fan is towards the water loss mechanism.

[0011] As a further improvement of the present invention, in another embodiment, a booster fan is also included. The booster fan is fixedly installed at the starting point of the washing mechanism, and the blowing direction is consistent with the conveying direction of the tea leaves in the washing mechanism, so as to blow the tea leaves into the dehydration mechanism. Several high-pressure atomizing water guns are evenly fixedly installed on the inner wall above the protective cover to spray and clean the tea leaves.

[0012] As a further improvement of the present invention, the dehydration mechanism is provided with multiple dehydration mechanisms that are connected in sequence. The drying fans in the dehydration mechanism are all fixedly installed below the tea inlet. The tea leaves falling from the outlet side of the dehydration mechanism can be conveyed to the next dehydration mechanism, thereby improving the drying efficiency and ensuring that the tea leaves are completely dried.

[0013] A method for treating water loss from tea leaves during washing and air rinsing includes the following steps: Step 1: Place the tea leaves to be processed into the water washing device; Step 2: The tea leaves are washed and sprayed with water through a high-pressure atomizing water washing channel; Step 3: The high-pressure atomizing water washing channel or the booster fan impacts the tea leaves, causing them to move forward in a suspended state within the water washing mechanism; Step 4: The rinsed tea leaves are blown into the dehydration mechanism in a suspended state by a conveyor fan; Step 5: The drying fan on one side of the dehydration mechanism blows up the tea leaves to be dehydrated and causes them to fall to the other side under gravity; Step Six: Transfer the tea leaves that have fallen from the other side of the dehydration mechanism into the next dehydration mechanism and repeat Step Five until the tea leaves are completely dried. Step 7: Put the dehydrated tea leaves into the subsequent withering machine for the next stage of processing.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the installation and arrangement of the high-pressure atomized water washing channel realizes the rinsing and cleaning of tea leaves and the tumbling and conveying of tea leaves in a suspended state, reducing the contact between tea leaves and equipment and improving the cleaning efficiency of dust, cobwebs, insects and other objects on tea leaves; the drying fan on one side blows air to screen the dried tea leaves on one side of the dehydration mechanism and makes them fall from the other end of the dehydration mechanism, preventing the dried tea leaves from mixing with the undried tea leaves and improving the dehydration efficiency. High-pressure atomizing water guns on the same side are alternately arranged on the flat and curved inner walls along the conveyor belt to prevent the tea leaves from breaking and falling due to impact, thus preventing them from tumbling forward in a suspended state. The high-pressure atomizing water washing channels on the first and second sides are symmetrically distributed to prevent the tea leaves from deviating to one side and ensure a stable movement trajectory. A wastewater tank is fixedly installed below the washing mechanism to store water droplets that fall when the high-pressure atomizing water washing channel rinses the tea leaves, preventing water droplets containing dirt and dust from being conveyed out of the washing mechanism with the tea leaves and affecting the rinsing and cleaning efficiency. A booster fan blows the tea leaves to increase the efficiency of tea leaf washing and suspension. Attached Figure Description

[0017] Specific Implementation Example 1: Please refer to Figures 1-6 This invention relates to an integrated washing and dehydration treatment machine, comprising a washing mechanism 1, a dehydration mechanism 2, a conveying channel 3, and several high-pressure atomizing washing channels 4. The two ends of the conveying channel 3 are respectively connected to the tail end of the washing mechanism 1 and the feed end of the dehydration mechanism 2. The conveying channel 3 is equipped with a conveyor belt capable of conveying tea leaves from the washing mechanism 1 to the dehydration mechanism 2. The washing mechanism 1 includes a conveyor belt 11 and a protective cover 12 fixedly fastened to the conveyor belt 11. The left side of the protective cover 12 along the conveying direction of the conveyor belt 11 is designated as a first side a, and the right side as a second side b. The lower ends of both sides of the protective cover 12 are flat, and the upper ends are arc-shaped. The high-pressure atomizing washing channel 4... The high-pressure atomized water washing channel 4 is a suspended movement channel formed on the conveyor belt 11 by setting the impact direction of high-pressure atomized water vapor. Under the impact direction of high-pressure atomized water vapor, the tea leaves are suspended and tumbled above the conveyor belt 11 towards the outlet. The high-pressure atomized water washing channel 4 can be implemented by selecting several high-pressure atomized water guns with multiple spray angles or several high-pressure atomized spray heads. In this embodiment, high-pressure atomized water guns are selected. The several high-pressure atomized water washing channels are set into four groups and fixedly installed on the inner wall of the plane and the inner wall of the arc surface of the first side a and the inner wall of the plane and the inner wall of the arc surface of the second side b, respectively. The four groups of high-pressure atomized water guns can be distributed as follows: The inner wall group of the first side a plane: the high-pressure atomizing water guns are arranged horizontally with the spray nozzles facing the end of the conveying process and tilted upward at 15°-45°, providing the tea leaves with forward propulsion and upward impact force, forming an alternating impact with the inner wall group of the first side a arc surface, causing the tea leaves to tumble during the forward movement. The first side a arc inner wall group: high-pressure atomizing water guns are arranged horizontally with the spray nozzles facing the end of the conveying process and tilted downwards at 15°-45° to provide forward propulsion. At the same time, the downward component force causes the tea leaves to fall back after rising, forming a dynamic balance. This prevents the tea leaves from leaving the effective cleaning area due to continuous lifting force, and makes the tea leaves turn up and down as they move forward, improving the uniformity of cleaning. The inner wall group of the second side b plane: the high-pressure atomizing water guns are arranged horizontally with the spray nozzles facing the end of the conveying process and tilted upward at 15°-45°. They are arranged alternately in the vertical direction with the inner wall group of the first side a arc surface, so that the tea leaves are subjected to alternating impact forces from up and down during the forward movement. The inner wall group of the second side b arc surface: the high-pressure atomizing water washing channel 4 is arranged horizontally with the spray nozzle facing the end of the conveying direction and tilted downward at 15°-45°. It is arranged in pairs with the inner wall group of the first side a plane in the vertical direction, so that the tea leaves are subjected to alternating impact forces from up and down during the forward movement. The high-pressure atomizing water washing channels 4 on the first side a and the second side b are arranged alternately and staggered in the vertical direction: that is, the sprayers on the inner wall of the arc surface of the first side a and the sprayers on the inner wall of the plane of the second side b are arranged opposite each other in the vertical direction, and the spray nozzles of each sprayer face the direction of the conveying end point, so that the tea leaves are subjected to continuous and alternating upward and downward impact forces during the forward movement, keeping them in a suspended and tumbling state; The arrangement of four sets of high-pressure atomizing water guns keeps the tea leaves suspended during the conveying process. Under the combined action of the water flow, the tea leaves tumble and move forward, reducing contact between the tea leaves and the machine and causing secondary contamination. This ensures both effective cleaning and prevents tea leaf accumulation.

[0018] In a further embodiment, such as Figure 5 As shown, the high-pressure atomizing water guns on the side are arranged alternately on the flat inner wall and the curved inner wall along the conveyor belt 11 to prevent the tea leaves from breaking and falling due to the impact force, thus preventing them from tumbling forward in a suspended state; the high-pressure atomizing water guns on the first side a and the second side b are installed in alternating symmetrical positions to prevent the tea leaves from deviating to one side and to ensure a stable movement trajectory.

[0019] In a further embodiment, such as Figure 2 As shown, a conveying fan 8 is fixedly installed on the bottom side of one end of the conveying channel 3 near the washing mechanism 1. The blowing direction of the conveying fan 8 is towards the dehydration mechanism 2, which can blow the tea leaves that have been rinsed by the washing mechanism 1 into the dehydration mechanism 2 along the conveying channel 3. The two ends of the conveying channel 3 are respectively connected to the tail end of the washing mechanism 1 and the feed end of the dehydration mechanism 2.

[0020] In a further embodiment, such as Figure 2As shown, a drying fan 6 is fixedly installed at the bottom of the dehydration mechanism 2 near the washing mechanism 1. The dehydration mechanism 2 is surrounded by a mesh surface on the top and sides, so that the air from the drying fan 6 is dispersed from the mesh surface to avoid turbulence. The tail end of the dehydration mechanism 2 is provided with an upward-sloping arc-shaped pipe. The air blown by the drying fan 6 is inclined upward along the pipe, blowing the tea leaves that are delivered to the dehydration mechanism 2 upward and causing the tea leaves to fall freely on the other side and be delivered out of the dehydration mechanism 2.

[0021] In a further embodiment, such as Figure 2 As shown, it also includes a water pump 5, which is fixedly installed on one side of the water washing mechanism 1, and several high-pressure atomizing water guns are connected to the water pump 5 through pipes.

[0022] In a further embodiment, such as Figure 4 As shown, a wastewater tank 7 is fixedly installed below the water washing mechanism 1 to store water droplets falling from the high-pressure atomized water washing channel 4 when rinsing the tea leaves, preventing water droplets with dirt and dust from being carried out of the water washing mechanism 1 with the tea leaves and affecting the rinsing and cleaning efficiency.

[0023] In a further embodiment, such as Figure 3 As shown, the conveyor belt 11 is made of mesh, and the mesh opening size is no larger than the size of the tea leaves, so that water droplets can leak from the mesh into the wastewater tank 7 for storage while preventing tea leaves from falling into the wastewater tank 7 with the mesh.

[0024] The tea leaves to be processed are put into the washing mechanism 1. The high-pressure atomizing washing channel 4 sprays water onto the tea leaves while providing impact force, causing the tea leaves to tumble and move forward in a suspended state within the washing mechanism 1. The water droplets contaminated with dirt are thrown into the wastewater tank 7 as the tea leaves tumble and move forward. As the high-pressure atomizing washing channel 4 continues to rinse the tea leaves, the tea leaves are blown in a suspended state by the conveying fan 8 along the conveying channel 3 to the dehydration mechanism 2. The drying fan 6 on one side of the dehydration mechanism 2 blows up the tea leaves to be dried. As the degree of dehydration increases, the weight of the tea leaves decreases, and the lighter tea leaves are blown to the highest point. At this time, the air force of the drying fan 6 is the weakest. The lighter tea leaves fall down on the other side of the dehydration mechanism 2 due to gravity. The dehydrated tea leaves are then put into the subsequent withering machine for the next stage of processing.

[0025] Specific Implementation Example 2: Please refer to Figure 7 The difference from Embodiment 1 is that it also includes a booster fan 9, which is fixedly installed at the starting point of the washing mechanism 1 and blows air in the same direction as the tea conveying direction in the washing mechanism 1, so as to blow the tea into the dehydration mechanism 2. Several high-pressure atomizing water guns that constitute the high-pressure atomizing washing channel 4 are evenly and alternately fixedly installed on the inner wall above the protective cover 12.

[0026] Specific Implementation Example 3: Please refer to Figure 8The difference from Embodiment 1 is that there are three dehydration mechanisms 2, which are arranged in a hierarchical manner. The drying fan 6 in each dehydration mechanism 2 is fixedly installed below the tea inlet. The tea leaves falling from the outlet side of the dehydration mechanism 2 can be conveyed to the next dehydration mechanism 2 to ensure that the tea leaves are completely dried.

[0027] Specific Implementation Example 4: Please refer to Figure 9 The difference from Embodiment 1 is that the high-pressure atomizing spray head used to realize the high-pressure atomizing water washing channel 4 is installed through the support steel pipe 10. The support steel pipe 10 is fixedly installed on the inner wall of the protective cover 12. Several inclined holes are opened on the pipe wall of the support steel pipe 10. The high-pressure atomizing spray head is directly installed in the support steel pipe 10 and the spray head is aligned with the inclined hole. The angle between the axis direction of the inclined hole and the horizontal direction is 15°-45°. The axis direction of each inclined hole is set according to the spray angle method of "the spray nozzles offset upward and the spray nozzles offset downward are continuously alternately arranged along the conveying direction". This makes the spray nozzles of the high-pressure atomizing spray head installed on it face the conveying end direction and offset upward or downward. By directly drilling inclined holes on the seamless steel pipe to install the spray head, the installation method of fixing multiple high-pressure atomizing water guns one by one in the water washing mechanism 1 is replaced, which effectively reduces the equipment manufacturing cost; or it can be achieved directly by spraying water mist through inclined holes without spray heads, which reduces costs.

[0028] It should be noted that the high-pressure atomization mentioned above can be achieved by pressurizing the liquid with an external high-pressure pump. The specific impact force and speed can be adjusted and preset to form the high-pressure atomization water washing channel 4 for the above purpose.
