Description

Technical Field

[0001] This utility model relates to the technical field of walnut kernel production equipment, specifically a peeling device and a continuous peeling production line for walnut kernels. Background Technology

[0002] The continuous walnut kernel peeling production line is a mature processing technology in the food processing industry, mainly used for the efficient removal of the astringent skin from the surface of walnut kernels. This technology typically begins with steam or hot water softening of the walnut kernels to loosen the seed coat. Subsequently, the material is fed into the core peeling equipment, which generally includes a peeling machine, a spray assembly, and a water circulation filtration assembly. The peeling machine has a casing containing a low-speed rotating cylinder. Spiral blades on the inner wall of the cylinder guide the walnut kernels to continuously tumble and rub against each other as they rotate. Simultaneously, several high-pressure nozzles arranged along the cylinder's axis in the spray assembly spray water into the cylinder, creating a hydraulic impact on the material. The combination of mechanical tumbling and water jet impact effectively removes the astringent skin from the walnut kernels. The peeling of peach kernels removes skin flakes and wastewater, which are discharged through the sieve holes in the cylinder wall and the drain outlet at the bottom of the machine. The wastewater then enters the water circulation filtration component, where it undergoes solid-liquid separation via filter plates or screens. The clean water is pumped back to the system for reuse in spraying, thus achieving the recycling of the cleaning water. The peeled walnut kernels are then continuously guided and propelled towards the end of the cylinder by the spiral blades inside, and are finally discharged continuously from the outlet at that end, entering the subsequent rinsing process. After further rinsing and hot air drying, a clean final product is obtained. This production line integrates physical friction, hydraulic cleaning, and resource recycling, forming a widely adopted and very mature existing technical solution in the industry.

[0003] In the prior art, in the process of realizing the above-mentioned water recycling, the prior art usually relies on setting up filter plates or filter screens to intercept walnut shell fragments carried in the water flow. Since the shelling process is continuous, the fragments will continuously accumulate on the filter media. In order to maintain the smooth flow of the filtration system and ensure the continuous operation of water circulation, the common practice is to arrange operators to clean the filter plates regularly. This maintenance operation includes using tools to scrape off the accumulated impurities and transfer them to a designated collection point.

[0004] However, the above-mentioned method of cleaning and maintenance relying on manual operation still has some drawbacks: manual cleaning is intermittent and difficult to match with the continuous production rhythm, which may lead to untimely cleaning actions. If the deposits on the filter media are not effectively removed, their filtration efficiency and water flow will gradually decrease, and in severe cases, it may cause the circulating water to overflow, which not only wastes water resources but may also affect the cleanliness and safety of the work site. In addition, frequent manual cleaning operations also increase the labor intensity and labor costs in the production process. Therefore, this utility model proposes a peeling device and a continuous peeling production line for walnut kernels to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a peeling device and a continuous peeling production line for walnut kernels to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a peeling device and a continuous peeling production line for walnut kernels, comprising: a peeling machine, a drain pipe fixedly connected to the bottom of the peeling machine, a water collection tank provided below the drain pipe, a fine-pore filter plate fixedly installed on the inner side of the top of the water collection tank, a waste discharge port opened on one side of the water collection tank, and a waste collection box provided below the waste discharge port. A pusher plate that can reciprocate along the surface of the fine-pore filter plate is provided on the upper side of the fine-pore filter plate. Several grooves are provided on the lower surface of the pusher plate. Each groove is fixedly connected to one end of a spring, and the other end of the spring is fixedly connected to a brush head. A drive assembly is provided on the other side of the water collection tank. The drive assembly is used to drive the pusher plate to reciprocate along the upper surface of the fine-pore filter plate so that the filter residue is pushed out from the discharge port.

[0007] Preferably, a feeding box is fixedly installed on the top of the peeling machine, and a discharge box is installed on the side of the peeling machine away from the collection box. A guide plate is provided on the outside of the discharge port, and the guide plate is fixedly connected to the side wall of the water collection box.

[0008] Preferably, an L-shaped frame is provided on the side of the water collection tank away from the guide plate. Both the L-shaped frame and the water collection tank are fixedly connected to the bottom of the peeling machine by a fixing rod. A guide groove is provided on the L-shaped frame.

[0009] Preferably, the drive assembly includes a waterproof motor, a drive gear fixedly connected to the output end of the waterproof motor, a driven gear plate meshing with the lower side of the drive gear, a transmission plate fixedly sleeved inside the driven gear plate, a push rod meshing with the lower side of the transmission plate for transmission, and a connecting rod fixedly connected to the end of the push rod.

[0010] Preferably, the waterproof motor is fixedly installed on one side of the L-shaped frame, and the other side of the L-shaped frame is slidably connected to the push rod through a guide groove. The transmission plate is rotatably connected to the L-shaped frame through a limit frame.

[0011] Preferably, one side of the bottom of the water collection tank is connected to one end of the water pump pipe, the other end of the water pump pipe is connected to the input end of the pump body, and the output end of the pump body is connected to the spray assembly installed inside the peeling machine.

[0012] A continuous walnut kernel peeling production line includes the aforementioned peeling equipment.

[0013] Compared with the prior art, the beneficial effects of this utility model are: The designed automatic cleaning mechanism effectively solves the problems caused by the reliance on manual intermittent cleaning of filter plates in existing technologies. By periodically and automatically driving the pusher plate and the brush head elastically connected to it to reciprocate along the surface of the filter plate, the accumulated walnut skin and shavings on the filter plate can be pushed into the collection box in a timely and automatic manner without interrupting the continuous operation of the production line. At the same time, the surface of the filter plate is brushed to prevent the filter holes from clogging. This automated process is stable and reliable, which not only avoids the decrease in filtration efficiency or overflow of circulating water that may be caused by untimely cleaning, ensuring the continuous and stable operation of the water circulation system and the effective use of water resources, but also fundamentally reduces the manual intervention and frequent maintenance required in the production process, helping to reduce labor intensity and labor costs.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Please see Figs. 1 to 4This utility model provides a technical solution: a peeling device and a continuous peeling production line for walnut kernels, comprising: a peeling machine 1, which is used to peel walnut kernels softened by steam or hot water; a drain pipe 2 is fixedly connected to the bottom of the peeling machine 1 to discharge the filtered water containing peel fragments; a water collection tank 3 is provided below the drain pipe 2; a fine-pore filter plate 4 is fixedly installed on the inner side of the top of the water collection tank 3 to filter the peel fragments; a discharge port 5 is provided on one side of the water collection tank 3 to discharge impurities; and a discharge outlet 5 is provided below the discharge port 5. The collection box 6 is used to collect impurities and skin flakes. A pusher plate 7 is provided on the upper side of the fine filter plate 4, which can reciprocate along the surface of the fine filter plate 4. Several grooves 8 are opened on the lower surface of the pusher plate 7. Each groove 8 is fixedly connected to one end of a spring 9. The other end of the spring 9 is fixedly connected to a brush head 10. The brush head 10 is slidably connected to the groove 8. A drive assembly is provided on the other side of the water collection box 3. The drive assembly is used to drive the pusher plate 7 to reciprocate along the upper surface of the fine filter plate 4 so that the filter residue is pushed out from the discharge port 5.

[0018] In operation, walnut kernels softened by steam or hot water are poured into the peeling machine 1, which contains a low-speed rotating cylinder. As the cylinder rotates, spiral blades on its inner wall guide the kernels to tumble and rub against each other. Simultaneously, several high-pressure nozzles arranged along the cylinder's axis spray water into the cylinder, creating a hydraulic impact on the material. The combination of mechanical tumbling and water jet impact effectively peels off the walnut kernels. The peeling debris and wastewater are discharged through the sieve holes in the cylinder wall and the drain pipe 2 at the bottom of the machine, flowing into the water collection tank 3. After passing through the fine-pore filter plate 4, the debris is filtered out, while the remaining water is recycled. At regular intervals, the machine is driven by the control drive component. The pusher plate 7 moves from the side away from the discharge port 5 to the side closer to the discharge port 5, pushing the accumulated dander out of the discharge port 5 and causing the impurities to fall into the collection box 6. Then the pusher plate 7 returns to its original position. As the pusher plate 7 moves, it drives the brush head 10, which is elastically connected at its bottom, to move along the surface of the fine pore filter plate 4. With the spring 9, the brush head 10 can always be in contact with the surface of the fine pore filter plate 4. Thus, while the accumulated material is pushed out, the brush head 10 can also clean the surface of the fine pore filter plate 4, thereby avoiding the clogging of the filter holes, ensuring the normal filtration of the fine pore filter plate 4, reducing the possibility of water overflow, and ultimately avoiding the trouble of manual operation and ensuring cleaning efficiency.

[0019] A feeding box 11 is fixedly installed on the top of the peeling machine 1 to facilitate the addition of materials. A discharge box 12 is installed on the side of the peeling machine 1 away from the collection box 6 to discharge the cleaned walnut kernels. A guide plate 13 is provided on the outside of the discharge port 5. The guide plate 13 is fixedly connected to the side wall of the water collection box 3. The guide plate 13 guides the peel residue pushed out by the pusher plate 7 to prevent it from flowing to the outside of the collection box 6. The collection box 6 can be pulled outward to facilitate the unified recycling of waste. An L-shaped frame 14 is provided on the side of the water collection box 3 away from the guide plate 13. The L-shaped frame 14 and the water collection box 3 are fixedly connected to the bottom of the peeling machine 1 by a fixing rod 15 to fix the L-shaped frame 14 and the water collection box 3. A guide groove 16 is provided on the L-shaped frame 14.

[0020] The drive assembly includes a waterproof motor 17 electrically connected to an external control device, a drive gear 18 fixedly connected to the output end of the waterproof motor 17, a driven gear 19 meshing with the lower side of the drive gear 18, a transmission disc 20 fixedly sleeved within the driven gear 19, a push rod 21 meshing with the lower side of the transmission disc 20 for transmission, and a connecting rod 22 fixedly connected to the end of the push rod 21. The waterproof motor 17 is fixedly mounted on one side of an L-shaped frame 14, which provides fixed support for the waterproof motor 17. The other side of the L-shaped frame 14 is slidably connected to the push rod 21 via a guide groove 16, which limits the movement of the push rod 21. The transmission disc 20 is rotatably connected to the L-shaped frame 14 via a limiting frame 23, which is fixedly mounted on the L-shaped frame 14. This supports and limits the transmission disc 20. A spiral protrusion 24 is fixedly connected to the lower surface of the transmission disc 20, and several sliding pins 25 are fixedly connected to the upper surface of the push rod 21. The spiral protrusion 24 and the sliding pins 25 mesh and transmit power. One end of the connecting rod 22 is fixedly connected to the push rod 21, and the other end of the connecting rod 22 passes through the water collection tank 3 and is fixedly connected to the push plate 7. The water collection tank 3 guides and limits the connecting rod 22. One side of the bottom of the water collection tank 3 is connected to one end of the water pumping pipe 26, and the other end of the water pumping pipe 26 is connected to the input end of the pump body 27. The output end of the pump body 27 is connected to the spray assembly set inside the peeling machine 1. The pump body 27 is electrically connected to the external control equipment, so that the filtered water collected in the water collection tank 3 is pumped back into the spray assembly set inside the peeling machine 1, thereby facilitating recycling.

[0021] An external controller directs the waterproof motor 17 to operate intermittently and periodically. In each working cycle, the controller first sends a start command to the waterproof motor 17, which then drives the drive gear 18 to rotate. The drive gear 18 meshes with the driven gear 19, causing the driven gear 19 to drive the transmission disc 20 to rotate under the limit of the limit frame 23. As the transmission disc 20 rotates, the spiral protrusion 24 at its bottom also rotates. Through the spiral change of the spiral protrusion 24 and the meshing and sliding of each sliding pin 25, the push rod 21 slides in the guide groove 16 opened on the L-shaped frame 14. Thus, the push rod 21 drives the connecting rod 22 to move synchronously, and the connecting rod 22 drives the pusher plate 7 to move. Driven by the forward and reverse rotation of the waterproof motor 17, the pusher plate 7 completes a complete reciprocating stroke from the starting position to the ending position and back. This stroke can push the material accumulated on the fine pore filter plate 4 into the collection box 6, and the pusher plate 7 resets. When the reciprocating stroke ends, the controller sends a stop command to the waterproof motor 17, causing the pusher plate 7 to stop at the initial standby position. Then, the controller enters a static waiting period. After this waiting period ends, the controller will automatically start the next identical working cycle. This cycle repeats itself, ultimately enabling the pusher plate 7 to clean the impurities and dander accumulated on the fine filter plate 4 at regular intervals. This timely cleaning reduces the hassle of manual intervention and lowers labor costs.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
