The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
As shown in fig. 1 to 3, the dynamic lift feeder 100 of the present application is used to feed a material of a target weight value into a stirring vessel 115, and the stirring vessel 115 is configured to have a plurality of feed ports 115a to simultaneously feed powder and liquid into the stirring vessel 115 through the feed ports 115 a. The dynamic lift feeder 100 includes: the device comprises a blanking pipe 101, a feeding part 102, a lifting platform 103, a lifting device 104 and a weighing device 107.
Specifically, the drop tube 101 is configured to have a drop passage through which material can pass to input material into the mixing vessel 115, and the drop tube 101 may be provided with a plurality of drops to input different materials into the mixing vessel 115; the feeding piece 102 is used for feeding materials into a blanking channel of the blanking pipe 101; the lifting platform 103 is used for supporting the stirring container 115 so that at least part of the blanking pipe 101 is inserted into the stirring container 115 from the feed inlet 115a when the stirring container 115 is lifted, so that leakage is avoided when materials are conveyed, and specifically, the feeding piece 102 adopts a bag-shaped structure; the lift platform 103 is also provided with a gear 1031 to position the wheels securing the blending container 115 to define the position of the blending container 115 on the lift platform 103.
The lifting device 104 is used for changing the position of the lifting platform 103, so as to adjust the relative position of the stirring container 115 and the blanking pipe 101; the weighing device 107 is used for weighing the stirring vessel 115 and the whole weight of the materials in the stirring vessel 115 in real time when feeding the materials to the stirring vessel 115; preferably, the lifting platform 103, the lifting device 104 and the weighing device 107 are independent of the vibration source (herein "independent of the vibration source" means that the lifting platform 103, the lifting device 104 and the weighing device 107 are not in direct or indirect contact with other vibration generating devices and that the three are not dependent on rigid support fixation).
By adopting the scheme, the weight of the stirring container 115 is directly weighed through the coordination of the lifting platform 103, the lifting device 104 and the weighing device 107, the lifting platform 103, the lifting device 104 and the weighing device 107 which affect the weighing precision are independent of a vibration source, and no direct connection exists between the lifting platform 103, the lifting device 104 and the weighing device 107 and the vibration source, so that the required weight of materials can be accurately obtained; in addition, the blanking pipe 101 is partially inserted into the stirring vessel 115 through the feed inlet 115a when feeding into the stirring vessel 115, and is not directly connected with the stirring vessel 115, so that vibration generated during blanking of the blanking pipe 101 is prevented from being transmitted to the stirring vessel 115, and the weighing and metering precision is further ensured.
As shown in fig. 4, as a specific embodiment, the lifting device 104 includes: a hydraulic cylinder device 105 and a pressure source device 106; the hydraulic cylinder device 105 is used for driving the lifting platform 103 to move so as to adjust the position of the blanking pipe 101 relative to the stirring container 115, when the stirring container 115 is required to be fed, the hydraulic cylinder device 105 lifts the lifting platform 103 so that at least part of the blanking pipe 101 stretches into the stirring container 115, and when the stirring container 115 is fed, the hydraulic cylinder device 105 drives the lifting platform 103 to descend so as to separate the blanking pipe 101 from the stirring container 115; the pressure source device 106 is connected with the hydraulic cylinder device 105 through a hydraulic pipeline and is used for providing a hydraulic medium for the hydraulic cylinder device 105; specifically, the pressure source device adopts a hydraulic station.
As shown in fig. 4, the dynamic lifting feeding device 100 of the present application further comprises a base 108 for supporting at least the hydraulic cylinder device 105 and the lifting platform 103; the base 108 and hydraulic cylinder assembly 105 are buried in a pit such that the height of the lift platform 103 in the initial state (with the stirring vessel 115 not raised) approximates the ground height, facilitating transfer of the stirring vessel 115 to the lift platform 103.
Specifically, the weighing device 107 includes at least one weighing sensor (not shown), and the mounting manner of the weighing sensor is not specifically limited, and the weighing sensor may directly measure the weight of the stirring vessel 115 or measure the weight of the lifting platform 103 and the whole stirring vessel 115 to indirectly obtain the weight of the stirring vessel 115.
As the material is conveyed in the down pipe 101, the down pipe 101 will inevitably generate slight vibrations. As shown in fig. 1 and 2, the blanking pipe 101 preferably includes: a receiving portion 1011 and a discharging portion 1012; the receiving part 1011 is provided with a feeding hole 101a for the feeding piece 102 to extend into the blanking channel; the discharging part 1012 is formed with a discharging hole 101b to input the material in the discharging passage into the stirring vessel 115; specifically, the outer diameter of the discharge portion 1012 is smaller than the inner diameter of the inlet 115a of the stirring vessel 115. In this way, the blanking pipe 101 is not in direct contact with the stirring vessel 115, so that vibration generated by the blanking pipe 101 is prevented from being transmitted to the stirring vessel 115, and the weighing precision of the stirring vessel 115 is ensured.
In the process of throwing the material into the stirring vessel 115, the liquid level in the stirring vessel 115 is gradually increased, so that the height of the blanking pipe 101 needs to be kept higher than the highest liquid level in order to avoid the blanking pipe 101 from immersing below the liquid level, however, when the discharge hole 101b of the blanking pipe 101 is far away from the liquid level, the weighing error caused by blanking impact can be caused.
As shown in fig. 1 and 2, as a preferred solution, the dynamically elevating feeding device 100 further includes: a level gauge 109 and a controller (not shown); the liquid level meter 109 is used for measuring the liquid level of the stirring vessel 115 to output a liquid level signal; the controller is used for controlling the pressure source device 106 to drive the hydraulic cylinder device 105 according to the liquid level signal so as to change the position of the stirring container 115 relative to the blanking pipe 101; the controller is electrically connected to the liquid level gauge 109, and the controller is electrically connected to the pressure source device 106.
By adopting the scheme, the liquid level meter 109 measures the depth of the solution in the stirring container 115, and the lifting platform 103 is controlled to gradually descend in the blanking process by transmitting back the liquid level value, so that the liquid level in the discharge hole 101b and the stirring container 115 is always kept at a certain distance, and the weighing error caused by blanking impact is reduced.
As shown in fig. 1 and 2, as a specific solution, the dynamically elevating feeding device 100 further includes: a flow meter 110 and an on-off valve 111; the flowmeter 110 and the switch valve 111 are respectively installed on the blanking pipe 101, and the flowmeter 110 is electrically connected to the controller and is used for measuring the flow of the material passing through the blanking channel and outputting a flow signal to the controller; the switch valve 111 is electrically connected to the controller, and is used for opening or closing the blanking channel under the control of the controller, and specifically, the switch valve 111 adopts a pneumatic ball valve; preferably, the on-off valve 111 is located between the flow meter 110 and the discharge port 101b of the drop tube 101, such that the time interval between the flow meter 110 sending a signal to the controller and then controlling the on-off valve 111 approximates the time that material is transferred from the flow meter 110 to the on-off valve 111, ensuring accuracy in material metering.
The weight signal output by the load cell can adjust the value of the flow meter 110 in real time so that the value of the flow meter 110 is always accurate. When the weight displayed by the load cell approaches the amount required by the customer, the flowmeter 110 will signal in advance to close the on-off valve 111.
As shown in fig. 1 and 2, the dynamic lifting feeding device 100 further preferably includes a material beating device 112, where the material beating device 112 is used to beat the feeding member 102 at a set frequency to promote flowability of the material. Specifically, the material beating device 112 includes: a flapper 1121 and a driver 1122; the clapping element 1121 is positioned at the periphery of the blanking pipe 101 so as to be capable of contacting the feeding element 102 when the feeding element 102 feeds into the blanking pipe 101; the driving piece 1122 is used for driving the beating piece 1121 to beat the feeding piece 102 at a preset frequency; the output end of the driving member 1122 is connected to the bat 1121, and specifically, the driving member 1122 may employ one of a cylinder or an electric putter.
Of course, alternatively, the material beating device 112 may use a vibrator to act on the material feeding member 102 or a motor to drive a cam to press the material feeding member 102, etc.
The dynamic lift feeder 100 further comprises a support frame 113, the support frame 113 being adapted to support the blanking pipe 101, the drive, etc.
As shown in fig. 1 and 2, the dynamic lifting feeding device 100 further comprises a lifting device 114; the lifting device 114 is used to lift the feeding element 102 to switch the feeding element 102 between the first position and the second position. The "first means" here means that the feeding member 102 is located at a position where the material is fed to the drop tube 101, and the "second means" here means that the feeding member 102 is located at a position separated from the drop tube 101.
Specifically, the lifting device 114 includes: a hoist 1141, a hoist rail 1142, and hoist rollers 1143; the steel wire rope of the winch 1141 is used for hoisting the feeding piece 102 through the hoisting ring, and then the height of the feeding piece 102 is adjusted when the winch 1141 winds the steel wire rope; a hoist rail 1142 is horizontally mounted to the support frame 113 for supporting the movement of the hoist 1141; the hoist 1141 is provided with a hoist roller 1143, so that the hoist 1141 can move along the hoist rail 1142, and further adjust the position of the feeding member 102 in the radial direction relative to the feeding pipe. In this way, the feeding member 102 can be accurately placed into the blanking pipe 101.
After the switch valve 111 closes the blanking channel, part of the material remaining in the blanking channel below the switch valve 111 will continue to run for a certain distance due to inertia and self weight and fall into the stirring container 115, which often causes that the actual material weight in the stirring container 115 after the switch valve 111 is closed still deviates from the required material weight.
As shown in fig. 1, 2 and 5, the present application also provides a feeding control method implemented by a dynamic lifting feeding device 100 for feeding a material of a target weight value into a stirring vessel 115, the dynamic lifting feeding device 100 comprising: the feeding part 102, a blanking channel, a weighing device 107, a controller, a flowmeter 110 and a switch valve 111; the controller is electrically connected to the flowmeter 110, the switch valve 111 and the weighing device 107.
Specifically, the feed control method includes the steps of:
s1: the flowmeter 110 measures the flow of the material passing through the blanking channel and outputs a flow signal to the controller;
s2: the controller compares the real-time weight value of the stirring vessel 115 acquired by the weighing device 107 with a preset weight value;
s3: when the real-time weight value reaches a preset weight value, the switch valve 111 is controlled to close the blanking channel;
preferably, the preset weight value is smaller than the target weight value, and the difference between the target weight value and the preset weight value is obtained according to the flow signal fed back by the flow meter 110.
