For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0042] The specific embodiments of the present application will be further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present application, but not to limit the scope of the present application.

[0043] As shown in Figure 1 - Figure 3 The soybean conveying online impurity removal device of the embodiment of the present application includes a first removing mechanism and a water supply mechanism. The first removing mechanism includes a settling container 10, a stirring assembly and a water distribution assembly. The settling container 10 can be in the shape of a jar, a barrel or a box, etc. The settling container 10 is provided with a feeding port 101 and a discharging port 102. The feeding port 101 is connected with a feeding mechanism, through which the soaked soybean material is supplied into the settling container 10. The discharging port 102 is arranged at the upper part of the settling container 10. The water distribution assembly is arranged at the lower part of the settling container 10. The stirring assembly is connected with the water distribution assembly. The stirring assembly drives the water distribution assembly to rotate. The water distribution assembly generates water flow waves from bottom to top in the settling container 10. The water-absorbed soybean is lighter than the stones and other impurities. The density of the water-absorbed soybean is close to that of water, about 1 g / cm 3 , and slightly has upward water flow force, so that it can flow upward and overflow the settling container 10. The density of the stone is generally 2.3-2.5 g / cm 3Compared with water and soaked soybeans, the soybeans in the soybean material are more than twice as much, so under the action of water flow waves, the soybeans and impurities such as stones in the soybean material are separated, the lighter soybeans float up, the soybeans flow upward along with the water flow to the discharge port 102, and flow out of the settling container 10; the heavier impurities sink downward to the bottom of the settling container 10, and the soybean material is subjected to impurity removal treatment; the water supply mechanism is provided with a water outlet 311, the water outlet 311 is located in the settling container 10, and the water outlet 311 is arranged from the lower side of the water distribution assembly towards the water distribution assembly, so that the water flowing out of the water outlet 311 can flow upward to the water distribution assembly, and then the water flow waves generated when the water distribution assembly rotates upward, so that the soybeans and impurities are separated.

[0044] In the present application, the rotation speed of the stirring assembly is adjusted according to the instantaneous feeding amount of the feeding mechanism, so as to adjust the rotation speed of the water distribution assembly, adjust the upward water flow wave flow speed, and make the discharge speed of the discharge port adapt to the instantaneous feeding amount of the feeding mechanism. Since the soybeans and impurities are separated under the action of the upward water flow waves, even if the feeding amount is large, the rotation speed of the stirring assembly driving the water distribution assembly increases, the water flow wave action increases, and the separation speed of the soybeans and impurities increases, thereby reducing the risk of discharging the material without impurity removal. In addition, the soybean material is continuously separated during conveying, and can continue to be conveyed after separation, which not only avoids the accumulation of soybean material in the settling container 10, but also reduces the risk of discharging the soybean material without impurity removal, and realizes the online connection of the upstream soybean soaking process and the downstream discharging conveying process, and realizes the continuous conveying of a large amount of material.

[0045] In the present embodiment, the soybean conveying online impurity removal device further comprises a controller, and the feeding mechanism and the stirring assembly are electrically connected with the controller; the controller controls the rotation speed of the stirring assembly according to the instantaneous feeding amount of the feeding mechanism, so as to make the discharge speed of the discharge port 102 adapt to the instantaneous feeding amount of the feeding mechanism, facilitate the adjustment of the discharge speed of the discharge port 102 according to the instantaneous feeding amount of the feeding mechanism, make the impurity removal of the soybean material by the stirring assembly and the water distribution assembly in the settling container 10 more sufficient, and improve the degree of automation.

[0046] In the present embodiment, the settling container 10 is in the shape of a tank, the lower part of the settling container 10 is in the shape of a cone, and the bottom of the settling container 10 is provided with a sewage valve 103, which facilitates the discharge of the impurities accumulated in the settling container 10.

[0047] In the present embodiment, as shown in Figure 1 and Figure 2As shown, the water distribution assembly comprises an impeller 14 connected with the stirring assembly, and an impeller water distribution cover 15 fixed with the settling container 10, the impeller 14 has a vertical rotation axis, and the impeller water distribution cover 15 is coaxially arranged on the outer circumferential side of the impeller 14, the lower part of the impeller water distribution cover 15 is provided with a water inlet, and the circumferential side of the impeller water distribution cover 15 is provided with a plurality of water distribution ports 151 arranged at an acute angle with the rotation axis of the impeller 14 in the vertical direction. The stirring assembly drives the impeller 14 to rotate in the impeller water distribution cover 15, the impeller 14 absorbs the water flowing out of the water outlet 311 of the water supply mechanism through the water inlet of the impeller water distribution cover 15, and the water is thrown to the water distribution ports 151 on the circumferential side of the impeller water distribution cover 15 under the action of the rotation of the impeller 14. Since the water distribution ports 151 are arranged at an acute angle with the rotation axis of the impeller 14 in the vertical direction, the water flowing out of the water distribution ports 151 has a vertical upward component, and a wave of water flow upward from bottom to top can be generated. The rotation frequency of the impeller 14 is in a certain positive ratio with the water supply flow rate, when the water supply flow rate is large, the impeller 14 rotates faster, when the water supply flow rate is small, the impeller 14 rotates slower. The lower limit of the rotation frequency of the impeller 14 is determined according to the requirement that the upward water flow generated thereby is sufficient to meet the requirement of soybean floating overflow, and the upper limit of the rotation frequency of the impeller 14 is determined according to the requirement that the upward water flow generated thereby is insufficient to make the stone float and overflow, so that the stone can be settled in the settling container 10.

[0048] Preferably, the plurality of water distribution ports 151 are uniformly arranged along the circumference, so that the generated upward water flow wave is uniform.

[0049] Preferably, in order to make the impeller 14 better absorb the water flowing out of the water outlet 311, a spray cap 3111 is installed at the water outlet 311, the spray cap 3111 is vertically installed, the spray cap 3111 is installed close to the impeller 14 directly below, and the water flows into the impeller water distribution cover 15 through the spray cap 3111, so as to facilitate the impeller 14 to absorb the water. The cap surface of the spray cap 3111 is mesh-shaped, and the diameter of a single mesh is 5mm-8mm. The distance between the spray cap 3111 and the impeller water distribution cover 15 is less than 10cm, so as to ensure that the water sprayed out of the spray cap 3111 can be sucked into the impeller water distribution cover 15 through the impeller 14.

[0050] In this embodiment, the impeller water distribution cover 15 is disc-shaped and hollow, the water inlet is arranged on the bottom plate of the impeller water distribution cover 15, and the water outlet 311 is arranged on the side wall of the impeller water distribution cover 15.

[0051] As Figure 1 and Figure 3As shown, the stirring assembly comprises a stirring motor 11 and a stirring shaft 13, the stirring motor 11 is in transmission connection with one end of the stirring shaft 13, specifically connected with the stirring shaft 13 through a shaft coupling 12, and an impeller 14 is coaxially installed on the stirring shaft 13. The stirring motor 11 is arranged at the top of the settling container 10, the stirring shaft 13 is coaxially arranged with the settling container 10, the impeller 14 is coaxially arranged with the stirring shaft 13, and when the stirring motor 11 drives the stirring shaft 13 to rotate, the impeller 14 rotates synchronously. The stirring motor 11 is a variable frequency motor, which can be frequency-converted according to the instantaneous feeding amount, the greater the instantaneous feeding amount, the faster the rotating speed, so as to control the rotating speed of the stirring shaft 13 and the rotating speed of the impeller 14, control the size of the water wave generated, and control the discharging speed. Among them, the water wave from bottom to top generated by the maximum rotating speed of the stirring motor 11 does not affect the stone settlement.

[0052] Further, a support 16 is fixed in the settling container 10, the other end of the stirring shaft 13 is rotatably installed on the support 16, and the impeller water distribution cover 15 is fixed on the support 16. The support 16 is fixed at the lower part of the settling container 10, the impeller water distribution cover 15 and the stirring shaft 13 are conveniently installed through the support 16, and the support 16 can provide support and limiting action for the stirring shaft 13, limit the axial and radial displacement of the stirring shaft 13, so that the impeller 14 only rotates in the horizontal plane with the stirring shaft 13, and horizontal sliding is avoided.

[0053] In this embodiment, the feeding mechanism comprises a quantitative feeding container 20 and a weight detection unit. The quantitative feeding container 20 can be a quantitative tank for containing the soaked and water-absorbed soybean material. The quantitative feeding container 20 is provided with a feeding port connected with the feeding port 101 of the settling container 10. The weight detection unit is used for detecting the weight of the material in the quantitative feeding container 20 and is electrically connected with the controller. The total amount of the soybean material contained in the quantitative feeding container 20 is constant, and the weight of the material in the quantitative feeding container 20 detected by the weight detection unit can obtain the amount of the soybean material flowing out from the quantitative feeding container 20. Therefore, the instantaneous flow rate of the quantitative feeding container 20 can be monitored through the quantitative feeding container 20 and the weight detection unit, and the instantaneous feeding amount can be obtained. The weight detection unit transmits a detection signal to the controller, and the controller adjusts the rotating speed of the stirring assembly according to the detection signal to control the discharging speed. When the instantaneous feeding amount is large, the rotating speed of the stirring assembly is increased to increase the discharging speed; when the instantaneous feeding amount is small, the rotating speed of the stirring assembly is reduced to reduce the discharging speed. The weight detection unit can be a weighing sensor 21.

[0054] Optionally, the material outlet is provided with a discharging valve 201, and the actual flow of the material is conveniently controlled by the opening range of the discharging valve 201. The opening range of the discharging valve 201 is determined according to the instantaneous flow obtained by the quantitative material container 20 and the weighing sensor 21, so that the actual feeding flow of the material always meets the pre-set flow requirement range.

[0055] Optionally, the lower side of the material outlet is provided with a feeding conveyor 22, and the soybean material flowing out of the material outlet flows to the feeding conveyor 22, and the material is conveyed to the feeding port 101 of the settling container 10 through the feeding conveyor 22, so that the feeding speed is kept constant, and the soybean material output by the material outlet can be prevented from entering the settling container 10 at one time, thereby avoiding that the instantaneous flow in the settling container 10 is too large.

[0056] In the embodiment, the water supply mechanism includes a water storage tank 30, a water supply pipe 31, a water supply pump 32 and a flow meter 33, wherein the water storage tank 30 is used for storing water; one end of the water supply pipe 31 is connected with the water storage tank 30, the other end of the water supply pipe 31 extends into the interior of the settling container 10, a water outlet 311 is arranged at the end of the water supply pipe 31 extending into the settling container 10, and a pipe valve 312 is installed on the water supply pipe 31; the water supply pump 32 is installed on the water supply pipe 31, and the water supply pump 32 is electrically connected with the controller; and the flow meter 33 is installed on the water supply pipe 31, and the flow meter 33 is electrically connected with the controller. The water in the water storage tank 30 is conveyed to the settling container 10 through the water supply pipe 31 by the water supply pump 32, and water is supplied to the water distribution assembly. The flow meter 33 is used for detecting the water supply flow of the water supply pipe 31 to the settling container 10, when the instantaneous feeding amount increases, the rotating speed of the stirring assembly increases, and the required water amount increases, and whether the current water supply flow of the water supply pipe 31 meets the water requirement of the water distribution assembly is obtained according to the water supply flow detected by the flow meter 33, and then the frequency of the water supply pump 32 is adjusted according to the detection result of the flow meter 33, so that the size of the water supply flow meets the water requirement of the water distribution assembly, and water energy consumption is saved. The required water amount is determined according to the instantaneous feeding amount of the feeding mechanism. When the instantaneous feeding amount increases, more water is required to carry the material out of the settling container 10, and more water is required to supplement the settling container 10, at this time, if the water supply flow detected by the flow meter 33 does not meet the water requirement corresponding to the instantaneous feeding amount, the frequency of the water supply pump 32 is increased, so that the water flow is met. When the instantaneous feeding amount decreases, the flow meter 33 detects the flow, and the frequency of the water supply pump 32 is adjusted to decrease, and when the instantaneous feeding amount becomes zero, the water supply pump 32 stops, so that water and electricity energy consumption is avoided.

[0057] In order to provide sufficient water into the settling vessel 10, preferably, the volume of the water storage tank 30 is more than 1.5 times of the volume of the settling vessel 10.

The high water level detection meter 301 is used for detecting the upper limit of the water level in the water storage tank 30, and the low water level detection meter 302 is used for detecting the lower limit of the water level in the water storage tank 30. A water replenishing valve 341 is installed on the water replenishing pipe 34, and the water replenishing valve 341 is electrically connected with the controller. When the low water level detection meter 302 detects that the water level in the water storage tank 30 is at the lower limit, the water replenishing valve 341 is controlled to be opened, and water is replenished into the water storage tank 30 through the water replenishing pipe 34. When the high water level detection meter 301 detects that the water level in the water storage tank 30 reaches the upper limit, the water replenishing valve 341 is controlled to be closed.

A plurality of water passing holes are formed on the lower part of the chute 40, and the diameter of the holes is not greater than 6 mm. The soybean material flowing out of the discharge port 102 flows to the chute 40, and the soybean is in a floating state on the chute 40. A very small amount of impurities such as stones which cannot be removed in the settling vessel 10 are deposited on the chute 40 due to the specific gravity, and are blocked on the upper part of the chute 40 by the partition pieces 41, so that secondary removal is realized. The lighter soybean flows downward along the chute 40, and when flowing through the lower part of the chute 40, the water is separated from the soybean, the water flows out through the water passing holes, and the soybean flows to the outlet of the chute 40. Preferably, the partition pieces 41 can be in a cylindrical shape, and there are more than 3 groups of partition pieces 41, and the interval distance between adjacent partition pieces 41 is at least 30 cm.

[0065] Further, the control method of the soybean conveying online impurity removal device further comprises: conveying the soybean material flowing out of the discharge port 102 of the settling container 10 to the chute 40, and performing secondary impurity removal treatment on the soybean material, so as to completely avoid incomplete removal of the impurities in the soybean material, and the impurities in the soybean material are blocked by the separation piece 41 in the chute 40, so that the soybeans in the soybean material flow out of the lower part of the chute 40; and at the same time, the water in the chute 40 is returned to the settling container 10, realizing the recycling of water. By performing two-stage impurity removal treatment on the soybean material, the removal of impurities in the soybean material is more complete.

[0066] Before the step of supplying the soaked soybean material into the settling container 10 and monitoring the instantaneous supply amount, the method further comprises the step of injecting circulating water so that the water flow between the settling container 10, the chute 40 and the water storage tank 30 reaches a dynamic balance. Specifically, the water storage tank 30 is filled with process water, the pipe valve 312 on the water supply pipe 31 is opened, and the water supply pump 32 is started. Under the action of the water supply pump 32, water flows through the spray cap 3111 to fill the settling container 10, and then flows back to the water storage tank 30 through the chute 40 and the flow guide cover 35.

[0067] Optionally, the step of supplying the soaked soybean material into the settling container 10 and monitoring the instantaneous supply amount comprises the steps of: placing the soaked soybean material in the quantitative container 20, and detecting the weight of the material in the quantitative container 20 by the weight detection device; and opening the discharge valve 201, and conveying the soybean material flowing out of the quantitative container 20 into the settling container 10. Since the initial total amount of the material in the quantitative container 20 is a constant value, the amount of the material flowing out of the quantitative container 20 can be obtained by monitoring the weight of the material in the quantitative container 20, i.e. the instantaneous supply amount. By automatically adjusting the discharge valve 201, the actual instantaneous supply amount can be controlled within the set required flow range.

[0068] Optionally, in the step of supplying water to the water distribution assembly, the water supply amount is monitored by the flow meter 33, and the water supply amount is adjusted according to the instantaneous supply amount. When the instantaneous supply amount is large, the rotation speed of the water distribution assembly is increased, the required water amount is increased, and the water supply amount is increased.

[0069] It should be noted that other specific embodiments of the control method of the soybean conveying online impurity removal device of the present application are substantially the same as the above-mentioned other specific embodiments of the soybean conveying online impurity removal device, and will not be repeated here.

[0070] The above only describes the preferred embodiments of the present application. It should be noted that those skilled in the art can make several improvements and replacements without departing from the technical principles of the present application, and these improvements and replacements should also be considered as the protection scope of the present application.
