Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of washing and screening devices, and particularly relates to a linear washing and screening device for Chinese jujube kernels. BACKGROUND

[0002] In the existing Chinese jujube kernel processing technology, a stirrer is usually used for soaking and washing operation. However, this method has some significant shortcomings. First, the soaking and washing method is less efficient than the screening method because it needs to stop and feed, which greatly reduces the production efficiency. Second, the floating impurities are easily attached to the surface of the Chinese jujube kernel during feeding, which affects the product quality. CONTENT OF THE INVENTION

[0003] The problem to be solved by the present application is that the existing Chinese jujube kernel uses a stirrer for soaking and washing operation, which not only reduces the efficiency due to stopping and feeding, but also easily attaches the floating impurities to the surface of the Chinese jujube kernel during feeding.

[0004] To solve the above technical problems, the present application provides a linear washing and screening device for Chinese jujube kernels, which comprises a rack, a plurality of rack plates arranged symmetrically on the top of the rack, a plurality of screen plate assemblies for removing impurities from Chinese jujube kernels arranged uniformly and spaced apart between the rack plates, a plurality of washing assemblies for washing the surface of Chinese jujube kernels arranged uniformly and spaced apart on the upper part of the screen plate assembly along the length direction, an accumulation bucket arranged at the bottom of the rack plate for collecting and accumulating the washing wastewater, a vibration assembly arranged on one side of the accumulation bucket for providing a vibration source, and the vibration direction of the vibration assembly is adjustable, and an inertia assembly arranged symmetrically between the rack plates for enhancing the vibration amplitude.

[0005] Since the linear washing and screening device of the present application is designed with the washing assembly, the screen plate assembly, the vibration assembly and the inertia assembly, it can not only realize continuous cleaning and screening of Chinese jujube kernels to improve production efficiency, but also keep the Chinese jujube kernels moving during the cleaning process to prevent impurities from adhering, thereby solving the problem that the existing Chinese jujube kernel uses a stirrer for soaking and washing operation, which not only reduces the efficiency due to stopping and feeding, but also easily attaches the floating impurities to the surface of the Chinese jujube kernel during feeding.

[0014] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example

[0015] This application relates to a linear washing and sieving device for jujube kernels, such as... Figures 1-7 As shown, the washing and screening device includes a frame 5. A frame plate 2 is symmetrically arranged on the top of the frame 5, and the frame plate 2 is inclined to facilitate the downward sliding of the jujube kernels under gravity. Multiple sets of screen plate assemblies 1 are evenly and spaced between the frame plates 2 for screening impurities from the jujube kernels. Multiple sets of rinsing components 7 are evenly and spaced along the length of the upper part of the screen plate assembly 1 for rinsing the surface of the jujube kernels. A collection hopper 6 is arranged at the bottom of the frame plate 2 for collecting and gathering the washing wastewater. To facilitate the movement of the jujube kernels along the surface of the screen plate assembly 1, a vibration component 8 is also arranged on one side of the collection hopper 6. A vibration source can be provided, and the vibration direction is adjustable. In order to increase the vibration amplitude, inertial components 4 are symmetrically arranged between the frame plates 2 to enhance the amplitude. The frame 5 is fixedly connected to the ground. In order to reduce the resonance of the frame 5, the frame 5 and the frame plate 2 are connected by vertically arranged springs 3. When in use, the jujube kernels are placed on the sieve plate assembly 1 at the top of the device, and the rinsing assembly 7 and the vibration assembly 8 are started. Under the action of vibration and rinsing, the jujube kernels move downward along the sieve plate assembly 1 and are cleaned at the same time. The wastewater after rinsing and the impurities removed are collected by the collection hopper 6 for convenient treatment.

[0016] The screen plate assembly 1 comprises a frame 11, a mesh plate 10, an inlet hopper 9 and an outlet plate 12. The frame 11 is arranged obliquely between the shelf plates 2 to provide a stable support structure for the entire screen plate assembly 1. The oblique angle of the frame 11 matches that of the shelf plates 2, ensuring that the jujube kernels can smoothly slide under the action of gravity. The frame 11 is made of high-strength material to withstand the vibration and impact force generated during the screening process. The mesh plate 10 is laid on the upper part of the frame 11 and is evenly distributed along the length of the frame 11. The mesh plate 10 has a screening effect, allowing cleaning water and small impurities to pass through while retaining the jujube kernels on the mesh plate 10. The mesh size of the mesh plate 10 is designed according to the size of the jujube kernels to ensure effective screening results. At the same time, the material of the mesh plate 10 has good wear resistance and corrosion resistance to ensure long-term use. One end of the frame 11 is arranged with a semi-enclosed inlet hopper 9 for introducing jujube kernels into the screen plate assembly 1. The inlet hopper 9 is designed in a semi-enclosed structure to facilitate the operator to evenly pour the jujube kernels onto the mesh plate 10, while preventing the jujube kernels from splashing during the pouring process. The other end of the frame 11 is arranged with an outlet plate 12 for receiving the jujube kernels after screening and cleaning. The outlet plate 12 is designed in an inclined manner to ensure that the jujube kernels can smoothly slide out and enter the next process.

[0017] The flushing assembly 7 comprises water pipes 13, spray heads 14 and a water pump. The water pipes 13 are made of metal pipes, which have good durability and pressure resistance. These water pipes 13 are evenly and spacedly arranged horizontally between the shelf plates 2 to ensure that the flushing water can uniformly cover the entire screen plate. The design of metal pipes also ensures the stability and durability of water flow, reducing maintenance problems caused by material aging or damage. At the upper part of the water pipes 13, spray nozzles are evenly and spacedly arranged towards the screen plate. These spray nozzles can spray water flow at an appropriate pressure and angle to the jujube kernels on the screen plate, effectively removing impurities on the surface of the jujube kernels. The design of the spray nozzles takes into account the distribution of water flow and impact force to ensure cleaning effect while not causing damage to the jujube kernels. The water pump is the power source of the entire flushing assembly 7, responsible for providing stable and sufficient pressure water flow to the water pipes 13. Through the water pump, it can ensure that the water quantity and pressure during the flushing process meet the cleaning requirements. The water pump is connected to the main pipe, which distributes water flow to each water pipe 13. In actual operation, the water pump is used for water supply operation. The water flow is distributed to each water pipe 13 through the main pipe and then sprayed to the jujube kernels on the screen plate by the spray nozzles. By adjusting the power of the water pump and the layout of the water pipes 13, the cleaning effect can be optimized to ensure the cleanliness of the jujube kernels.

[0018] The vibration assembly 8 comprises a base plate 16, a clamping plate 17 and a vibrator 15. The base plate 16 is fixedly arranged on one side of the collecting hopper 6 as a support base of the whole vibration assembly 8. The base plate 16 has sufficient strength and stability to withstand the vibration force generated by the vibrator 15 and uniformly transmit the vibration force to the collecting hopper 6. The clamping plate 17 is arranged on the upper part of the base plate 16 and can rotate around the base plate 16. The clamping plate 17 and the base plate 16 are rotationally connected through a specific connecting mode (such as bearing, hinge, etc.), so that the clamping plate 17 can freely adjust the angle within a certain range. This design not only facilitates the installation and adjustment of the vibration assembly 8, but also can adapt to the needs of different working scenes to a certain extent. An arc-shaped through slot 18 is formed in the upper part of the clamping plate 17. A bolt connected with the base plate 16 is arranged in the through slot. The bolt passes through the arc-shaped through slot 18 and is threadedly connected with the base plate 16, so as to fix the clamping plate 17 on the base plate 16. This connecting mode not only ensures the stability between the clamping plate 17 and the base plate 16, but also allows the clamping plate 17 to be finely adjusted relative to the base plate 16 within a certain range. The vibrator 15 is arranged in the central position of the upper part of the clamping plate 17 and is connected with the clamping plate 17. The vibrator 15 is the core component of the vibration assembly 8 of the present application and is used to generate vibration force and drive the whole assembly to vibrate. The vibrator 15 can adopt various existing vibration devices (such as electric vibrator 15, pneumatic vibrator 15, etc.) according to actual needs. When the vibrator 15 is started, the vibration force generated by the vibrator 15 is transmitted to the base plate 16 through the clamping plate 17, and then to the collecting hopper 6. Since the clamping plate 17 can rotate around the base plate 16, the transmission direction and angle of the vibration force can be adjusted to adapt to different working needs. At the same time, the design of the arc-shaped through slot 18 and the bolt makes the connection between the clamping plate 17 and the base plate 16 have certain flexibility and adjustability, further improving the adaptability and use convenience of the vibration assembly 8. It should be noted that if the vibrator 15 is arranged at the position shown in the figure, the vibration direction adjustment effect is not ideal. In order to realize the adjustment of the vibration direction of the vibrator 15, the vibrator 15 can be replaced to other positions of the collecting hopper 6, such as the front and rear sides of the collecting hopper 6, and is not limited to the position shown in the figure.

[0019] The inertia assembly 4 includes a cover 19, inertia wheels 21, counterweights 20 and connecting rods 22, the cover 19 is sleeved outside the inertia wheels 21 and connected with the shelf plate 2, which is used to protect the internal structure of the inertia assembly 4 and prevent the inertia wheels 21 or counterweights 20 from flying out, the cover 19 can be made of metal or non-metal material and has sufficient strength and corrosion resistance, the inertia wheels 21 are symmetrically arranged outside the shelf plate 2 and connected with the shelf plate 2 through bearings, which enables the inertia wheels 21 to rotate freely under the support of the bearings, thereby generating stable vibration effect, the number and size of the inertia wheels 21 can be adjusted according to actual requirements to achieve different vibration amplitudes and frequencies, the connecting rods 22 are connected between the inertia wheels 21 and have a universal joint structure, the design of the universal joint enables the connecting rods 22 to flexibly drive in different directions, thereby ensuring the synchronous rotation between the inertia wheels 21, the connecting rods 22 can be made of high-strength material to withstand the torque and shear force generated during the rotation of the inertia wheels 21, the counterweights 20 are coaxially arranged on one side of the inertia wheels 21 and eccentrically arranged relative to the rotation center of the inertia wheels 21, the mass and eccentricity of the counterweights 20 can be adjusted as required to change the vibration characteristics and mechanical properties of the vibration assembly, when the inertia wheels 21 rotate, the counterweights 20 will generate a periodic vibration force due to the centrifugal force, thereby driving the entire assembly to vibrate, when the inertia assembly 4 starts, the motor or other power source drives the inertia wheels 21 to rotate, due to the eccentric arrangement of the counterweights 20, the inertia wheels 21 will generate a periodic vibration force during rotation, this vibration force is transmitted to the shelf plate 2 through the connecting rods 22 and bearings, and then transmitted to the working equipment connected therewith, thereby realizing the vibration-assisted process.

[0020] In use, turn on the power switch to start the linear washing and screening device, adjust the vibration frequency and amplitude to the appropriate working state to ensure the uniform distribution and effective screening of the jujube kernels on the screen, add an appropriate amount of clean water to the screen through the water inlet system of the device to start cleaning the jujube kernels, the clean water fully contacts the jujube kernels to remove the dirt and impurities on the surface, under the action of linear vibration, the jujube kernels are screened on the screen, the smaller impurities and unqualified jujube kernels fall into the collection tank below through the screen holes, while the qualified jujube kernels move forward along the screen and finally discharged from the discharge port, periodically clean the impurities and unqualified jujube kernels in the collection tank, collect the qualified jujube kernels for subsequent drying, packaging and other treatments.
