Description

Technical Field

[0001] The invention belongs to the technical field of bean sprout pre-growth processing equipment, and in particular relates to an automatic bean washing, soaking and bean sorting device. Background Art

[0002] In the prior art, the raw beans are cleaned and soaked by manpower. During the cleaning and soaking process, the processes of loading, adding water, changing water, stirring, and discharging are all completed manually. The cleaning and soaking process is labor-intensive and has low work efficiency, which cannot meet the needs of modern mechanized production. At the same time, after the cleaning and soaking is completed, the raw beans need to be transferred to a dedicated bean sprout growing device manually, which is labor-intensive.

[0003] The Chinese invention patent with application number 201910203302.1 provides a regulating valve, wherein a flow channel is defined in the valve body; the valve seat is arranged in the flow channel and a flow guide hole connected to the flow channel is arranged on the valve seat; the valve core is rotatably arranged on the valve seat, and the valve core can conduct or close the flow guide hole when the valve core rotates. According to the regulating valve of the invention, the valve core is rotatably arranged on the valve seat, and the valve core can conduct or close the flow guide hole when the valve core rotates, and the valve is opened or closed by rotating the valve core. The seal between the rotary valve core and the valve seat is a surface seal, and the sealing contact surface is large, which has good sealing performance and prolongs the service life of the valve core and the valve seat. The rotary valve core and the valve seat perform a plane shearing motion during use, and the deposits attached to the surface can be removed during the movement of the two, which is not easy to cause clogging, and can withstand a large valve body pressure difference and a high temperature environment. The regulating valve does not require high processing accuracy, is easy to process, and is easy to install and maintain. However, the regulating valve in the patent can only filter water or can only allow materials and water to pass through at the same time. Only one of the two situations can be possible, not both.

[0004] The Chinese utility model patent with application number 202020775257.5 discloses an automatic soybean washing, soaking and conveying device, including a bean washer, a bean soaking tank and a water bean separator, wherein the bean washer is connected to the bean soaking tank via a conveying pipe 1, and the bean soaking tank is connected to the water bean separator via a conveying pipe 2, wherein a control valve 1 and a conveying pump 1 are provided on the conveying pipe 1, and a control valve 2 and a conveying pump 2 are provided on the conveying pipe 2.

DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention.

[0043] In the description of the present invention, it is necessary to understand that if it involves orientation description, the orientation or position relationship indicated by, for example, up, down, front, back, left, right, etc. is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0044] In the description of the present invention, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed" etc. are understood as not including the number itself, and "above", "below", "within" etc. are understood as including the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0045] The present invention will now be further described with reference to the embodiments and the accompanying drawings:

[0046] like Figures 1 to 11As shown, a bean washing and soaking device comprises a bean washing and soaking bin 2, a discharge channel 25 at the bottom of the bean washing and soaking bin 2 and a water supply device for the bean washing and soaking bin 2, a filter discharge switching valve is arranged on the upper part of the discharge channel 25, the filter discharge switching valve comprises a valve seat and a valve plate, a filter hole is arranged on the valve plate to form a filter valve plate, and a common valve is connected to the lower part of the discharge channel 25, when the common valve is opened and the filter valve plate is closed, water can pass through the filter valve plate, while the beans are blocked by the filter valve plate, and when the filter valve plate is opened, water and beans can pass through the filter discharge switching valve. For example: the filter discharge switching valve can be a butterfly valve, but it is necessary to set a filter hole on the valve core, so that the beans cannot pass through the filter hole, but water can pass through, so that by rotating the valve core, it can be realized that only water is filtered but not the beans, or both water and beans can pass through; the filter discharge switching valve can also be a gate valve, but it is necessary to set a filter hole on the gate plate, so that the beans cannot pass through the filter hole, but water can pass through, so that by the action of the gate plate, it can be realized that only water is filtered but not the beans, or both water and beans can pass through.

[0047] An air nozzle 13 of an air blowing device is arranged around the filter discharge switching valve, and the air blowing device comprises a high-pressure blower 1 and an air nozzle 13 connected to the high-pressure blower 1. The high-pressure blower is fixedly connected to the upper end of the bean washing and soaking bin 2, and the air nozzle 13 is fixedly connected to the lower end of the bean washing and soaking bin 2. The air blowing device is located at the bottom of the bean washing and soaking bin 2, and the beans are cleaned by blowing air to the bottom. A filter can be arranged on the air nozzle 13 to prevent the beans from entering the air nozzle 13 and expanding in the soaked beans to block the air nozzle 13. At least one high-pressure blower 1 can be arranged, and two can be arranged, one is usually used, and the other is standby.

[0048] like Figure 8 , Fig.10 As shown, when the filter valve plate is closed, the height h of the discharge channel 25 on the upper part of the filter valve plate is smaller than the maximum cross-sectional diameter d of the beans along the long axis. The gap j between the periphery of the filter valve plate and the inner wall of the discharge channel 25 is smaller than the maximum cross-sectional diameter d of the beans along the long axis. This is to prevent the beans from gathering in these places and to prevent the beans from swelling and blocking these places during the subsequent soaking process. If it is soybeans, the height h and the gap j are both smaller than the maximum cross-sectional diameter d of the soybeans along the long axis; if it is mung beans, the height h and the gap j are both smaller than the maximum cross-sectional diameter d of the mung beans along the long axis; if it is a mixture of soybeans and mung beans, the height h and the gap j are both smaller than the maximum cross-sectional diameter d of the mung beans along the long axis. These are just some examples mentioned to make this application clearer, but they are not all cases.

[0049] like Fig. 9As shown, the structure of the filter discharge switching valve is a quick-opening rotary valve 14 structure, which includes a valve seat plate 27 and a valve core plate 26. The valve seat plate 27 and the valve core plate 26 are coaxially relatively rotating quick-opening rotary valves 14. The periphery of the valve seat plate 27 is fixed in the discharge channel 25. The valve seat plate 27 is provided with a guide hole area 28 and a filter hole area 29. The valve core plate 26 is also provided with a guide hole area 28 and a filter hole area 29. The structures of the valve seat plate 27 and the valve core plate 26 can be consistent, but the area of ​​the filter hole area 29 of the valve core plate 26 must be greater than or equal to the area of ​​the guide hole area 28 of the valve seat plate 27, so that when the guide hole area 28 of the valve seat plate 27 is not connected with the guide hole area 28 of the valve core plate 26, the beans can be prevented from passing through. When the guide hole area 28 of the valve seat plate 27 is connected with the guide hole area 28 of the valve core plate 26, the beans pass through the guide holes. When the guide hole area 28 of the valve seat plate 27 is not connected with the guide hole area 28 of the valve core plate 26, only water can pass through the filter holes, and the beans cannot pass through the filter holes.

[0050] The upper end of the bean washing and soaking bin 2 is fixedly connected to the cross beam 7, and a driving motor 8 is arranged on the cross beam 7. The output shaft of the driving motor 8 is fixedly connected to the valve stem 12, and the valve stem 12 is fixedly connected to the valve core plate 26. The filter discharge switching valve is controlled by the motor drive. The ordinary valve is an electric valve that can control the flow of water and beans. The lower end of the bean washing and soaking bin 2 is fixedly connected to the support column 3.

[0051] A bean soaking sterilizing device is arranged at the upper end of the bean washing and soaking bin 2, and the bean soaking sterilizing device comprises a medicine tank 11 and a rotating motor 10, the rotating motor 10 is fixedly connected to the upper end of the bean washing and soaking bin 2, and the rotating shaft of the rotating motor 10 is fixedly connected to the outer wall of the medicine tank 11. Sterilization drugs are put into the medicine tank 11 manually and regularly, so that the sterilization drugs can be poured into the bean washing and soaking bin 2 when needed.

[0052] The water supply device includes a bean washing water supply device, a bean soaking water supply device and a bean placing circulating water device. The bean washing water supply device, the bean soaking water supply device and the bean placing circulating water device all include a water tank 5 and a water pump 18 arranged in the water tank 5.

[0053] The inner side of the upper end of the bean washing and soaking bin 2 is fixedly connected to the spray annular pipe 9, and the water pump 18 is connected to the water inlet of the spray annular pipe 9 through a hose. The water tank 5 of the bean circulating water device has a conical bottom, and a drain valve is arranged at the lower end of the water tank 5 of the bean circulating water device. The spray annular pipe 9 is installed around the inner wall of the bean washing and soaking bin 2, so that in the bean washing or bean sorting stage, the spray annular pipe 9 can spray water on the inner wall of the bean washing and soaking bin 2, so that the beans or impurities adhering to the inner wall of the bean washing and soaking bin 2 can be washed away, ensuring that all the beans in the bean washing and soaking bin 2 are discharged and the bean washing and soaking bin 2 is clean. Or the water pump 18 is fixedly connected to a stainless steel water pipe with a downward outlet, and the spray annular pipe 9 is fixedly connected to a water receiving pipe with an upward inlet, and the stainless steel water pipe is inserted into the water receiving pipe to form a sleeve connection. Whether the water pump 18 is connected to the water inlet of the spray ring pipe 9 through a hose, or the stainless steel water pipe is inserted into the water connecting pipe to form a sleeve connection, it is to reduce the influence of these factors on the weighing. At the same time, it should be clear that in the pre-processing stage of the beans, that is, in the washing, soaking and sorting stage of the beans, the weighing accuracy can be very small and the accuracy requirement is not high, that is, the weighing error can be large, which is different from the weight accuracy requirement of the reactants in the chemical reaction.

[0054] The outlet of the discharge channel 25 is provided with a bean-separating device. At least one set of the bean-separating device is provided, and the number of the corresponding discharge channels 25 is consistent with the number of the bean-separating devices.

[0055] The bean-dispensing device includes a dispensing trolley 6, which is arranged at the outlet of the discharging channel 25. The dispensing trolley 6 is arranged on a working bracket 16. A position sensor is arranged on the working bracket 16, and the position sensor is used to detect the position information of the dispensing trolley 6. The dispensing trolley 6 includes a mobile frame 19 and a material distribution bin 20. The material distribution bin 20 is arranged on the mobile frame 19. A weighing sensor a22 is arranged between the material distribution bin 20 and the mobile frame 19. The mobile frame 19 is provided with four gears, at least two of which are driving gears. The reduction motor 15 drives the driving gear through the transmission rod 17. The reduction motor 15 is fixedly connected to the mobile frame 19, and the driving gear is meshed with a rack fixed on the working bracket 16.

[0056] The lower end of the cloth bin 20 is fixedly connected to the mesh belt conveyor 21, which is driven by a driving device 24. The two side panels extending from the lower end of the cloth bin 20 serve as the frame of the mesh belt conveyor 21. The diameter of the filter hole on the mesh belt of the mesh belt conveyor 21 is smaller than the minimum diameter of the beans. The cloth bin 20 is provided with a discharge port 23 output with the mesh belt. The mesh belt conveyor 21 is an ordinary conveyor, but its conveyor belt has meshes, which can be called a mesh belt. There are a large number of related products in the existing market, which will not be repeated in this application. A bean sprout growth barrel is set below the moving track of the bucket car 6. The bean sprout growth barrel serves as a growth container for the later bean sprouts. At the same time, the position of the bean sprout growth barrel is consistent with the installation position of the position sensor. The support column 3 includes an upper support and a lower support. A weighing sensor b4 is set between the upper support and the lower support, so that the amount of water for washing and soaking beans, the number of beans added, and whether there are any beans that have not been released in the washing and soaking bean bin 2 can be known.

[0057] The bean soaking water supply device also includes a water level sensor, and a temperature sensor and a bean soaking water temperature control valve are also arranged in the water tank 5 of the bean soaking water supply device. The water in the bean soaking water supply device is obtained by mixing hot water and cold water supplied by a boiler, and the bean soaking water temperature control valve is similar to a hot and cold water valve for bathing. According to the feedback of the temperature sensor, the bean soaking water temperature control valve changes the temperature of the water in the bean soaking water supply device by changing the inflow of hot water and the inflow of cold water.

[0058] Weighing sensor a22, weighing sensor b4, position sensor, water level sensor, bean soaking water temperature control valve, temperature sensor, water pump 18, high pressure fan 1, driving motor 8, rotating motor 10, reduction motor 15, mesh belt conveyor 21, electric valve and drain valve are all electrically connected to the programmable controller, and the programmable controller is electrically connected to the human-machine interface and the power supply module respectively;

[0059] The programmable controller is connected to the weighing sensor a22 for weighing the beans in the bucket car 6;

[0060] The programmable controller is connected to the weighing sensor b4 for weighing the beans in the bean washing and soaking bin 2;

[0061] The programmable controller is connected to the position sensor to detect the position of the bucket truck 6;

[0062] The programmable controller is connected to the water level sensor to control the water level in the water tank 5 of the bean soaking water supply device;

[0063] The programmable controller is connected to the bean soaking water temperature control valve to control the water temperature in the water tank 5 of the bean soaking water supply device;

[0064] The programmable controller is connected to the temperature sensor to detect the water temperature in the water tank 5 of the bean soaking water supply device;

[0065] The programmable controller is connected to the motor group to control the rotation of the motor to complete the functions of water intake into the bean washing and soaking bin 2, regular air blowing to clean the beans, opening and closing the filter discharge switching valve, pouring sterilization drugs into the bean washing and soaking bin 2, moving the bucket car 6 and placing beans into the bean sprout growth barrel;

[0066] The programmable controller is connected to the water pump 18 to complete the function of water intake into the bean washing and soaking bin 2;

[0067] The programmable controller is connected to the high-pressure blower 1 to complete the function of regular air blowing and cleaning of the beans;

[0075] The programmable controller is connected to the power supply module to provide a DC power supply for the programmable logic controller.

[0076] Because there are multiple high-pressure blowers, the programmable controller needs to be connected to multiple high-pressure blowers. At the same time, there are also multiple bucket trucks. The following are related to a bucket truck: position sensor, electric valve, reduction motor, mesh belt conveyor, weighing sensor a. If multiple bucket trucks need to be set up, the programmable controller also needs to be connected to the above components separately.

[0077] A weighing signal conversion module a is set between the weighing sensor a22 and the programmable controller, and a weighing signal conversion module b is set between the weighing sensor b4 and the programmable controller; a temperature conversion module is set between the temperature sensor and the programmable controller; a driving module is set between the reduction motor 15 and the programmable controller; and the human-machine interface is a touch screen.

[0078] The working process of the present invention is as follows:

[0079] Step 1: Place beans into the bean washing and soaking bin 2 (the beans can be placed into the bean washing and soaking bin using a lift in the prior art), start the water pump 18 of the bean washing and soaking water supply device to inject water into the bean washing and soaking bin 2, then open the electric valve to discharge the water used to wash the beans into the water tank 5 of the bean circulating water device, then open the drain valve to discharge the waste water, repeat this 1 to 3 times until the beans are washed, and close the drain valve and the electric valve;

[0080] Step 2: Heat the water in the water tank 5 of the bean soaking water supply device to 40-50°C (in summer, the water temperature can be set slightly lower, and in winter, the water temperature can be set slightly higher), and then inject the water in the water tank 5 of the bean soaking water supply device into the bean washing and soaking bin 2;

[0081] Step 3: Move the bucket trolley 6 to the top of the water tank 5 of the bean circulating water device, and open the electric valve, the filter discharge switching valve, and the water pump 18 of the bean circulating water device at the same time. The beans and the bean soaking water flow into the bucket trolley 6 through the discharge channel 25, and the beans remain in the material distribution bin 20. The bean soaking water flows into the water tank 5 of the bean circulating water device. At the same time, the water pump 18 of the bean circulating water device injects the bean soaking water in the water tank 5 of the bean circulating water device into the bean washing and soaking bin 2 for continuous discharge of the beans until the beans in the bean washing and soaking bin 2 are completely discharged, and then close the electric valve, the filter discharge switching valve, and the water pump 18 of the bean circulating water device;

[0082] Step 4: The position sensor detects the position of the bucket trolley 6. When the bucket trolley 6 moves to the position of the set position sensor, the bucket trolley 6 stops moving, starts the mesh belt conveyor 21, and allows the beans on the mesh belt conveyor 21 to fall into the corresponding bean sprout growing barrel. When the weighing sensor a22 determines that the beans in the bean sprout growing barrel have reached the set mass, the mesh belt conveyor 21 stops moving, and then the bucket trolley 6 continues to move to the next set position sensor position, and continues to put beans, and repeats this process until each bean sprout growing barrel is fully loaded.

[0083] Among them, step three and step four are carried out in coordination. The mass of the beans put into the cloth bin 20 is measured by the weighing sensor a22. When the mass of the beans reaches the set value, the washing and soaking bean bin 2 stops discharging, and the dividing bucket trolley 6 starts to divide the materials. When there are no beans in the cloth bin 20, the dividing bucket trolley 6 moves to the exit of the discharge channel 25, and the washing and soaking bean bin 2 continues to discharge into the dividing bucket trolley 6, and the dividing bucket trolley 6 continues to divide the materials. This is repeated until the beans in the washing and soaking bean bin 2 are divided.

[0084] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, which should also be regarded as the scope of protection of the present invention.
